GHSA-XPPV-4JRX-QF8M
Vulnerability from github – Published: 2026-04-16 01:35 – Updated: 2026-04-24 20:51Summary
wger exposes a global configuration edit endpoint at /config/gym-config/edit implemented by GymConfigUpdateView. The view declares permission_required = 'config.change_gymconfig' but does not enforce it because it inherits WgerFormMixin (ownership-only checks) instead of the project’s permission-enforcing mixin (WgerPermissionMixin) .
The edited object is a singleton (GymConfig(pk=1)) and the model does not implement get_owner_object(), so WgerFormMixin skips ownership enforcement. As a result, a low-privileged authenticated user can modify installation-wide configuration and trigger server-side side effects in GymConfig.save().
This is a vertical privilege escalation from a regular user to privileged global configuration control. The application explicitly declares permission_required = 'config.change_gymconfig', demonstrating that the action is intended to be restricted; however, this requirement is never enforced at runtime.
Affected endpoint
The config URLs map as follows.
File: wger/config/urls.py
patterns_gym_config = [
path('edit', gym_config.GymConfigUpdateView.as_view(), name='edit'),
]
urlpatterns = [
path(
'gym-config/',
include((patterns_gym_config, 'gym_config'), namespace='gym_config'),
),
]
This resolves to:
/config/gym-config/edit
Root cause
The view declares a permission but does not enforce it
File: wger/config/views/gym_config.py
class GymConfigUpdateView(WgerFormMixin, UpdateView):
model = GymConfig
fields = ('default_gym',)
permission_required = 'config.change_gymconfig'
success_url = reverse_lazy('gym:gym:list')
title = gettext_lazy('Edit')
def get_object(self):
return GymConfig.objects.get(pk=1)
The permission string exists, but WgerFormMixin does not check permission_required.
The project’s permission mixin exists but is not used
File: wger/utils/generic_views.py
class WgerPermissionMixin:
permission_required = False
login_required = False
def dispatch(self, request, *args, **kwargs):
if self.login_required or self.permission_required:
if not request.user.is_authenticated:
return HttpResponseRedirect(
reverse_lazy('core:user:login') + f'?next={request.path}'
)
if self.permission_required:
has_permission = False
if isinstance(self.permission_required, tuple):
for permission in self.permission_required:
if request.user.has_perm(permission):
has_permission = True
elif request.user.has_perm(self.permission_required):
has_permission = True
if not has_permission:
return HttpResponseForbidden('You are not allowed to access this object')
return super(WgerPermissionMixin, self).dispatch(request, *args, **kwargs)
GymConfigUpdateView does not inherit this mixin, so none of the login/permission logic runs.
The mixin that is used performs only ownership checks, and GymConfig has no owner
File: wger/utils/generic_views.py
class WgerFormMixin(ModelFormMixin):
def dispatch(self, request, *args, **kwargs):
self.kwargs = kwargs
self.request = request
if self.owner_object:
owner_object = self.owner_object['class'].objects.get(pk=kwargs[self.owner_object['pk']])
else:
try:
owner_object = self.get_object().get_owner_object()
except AttributeError:
owner_object = False
if owner_object and owner_object.user != self.request.user:
return HttpResponseForbidden('You are not allowed to access this object')
return super(WgerFormMixin, self).dispatch(request, *args, **kwargs)
File: wger/config/models/gym_config.py
class GymConfig(models.Model):
default_gym = models.ForeignKey(
Gym,
verbose_name=_('Default gym'),
# ...
null=True,
blank=True,
on_delete=models.CASCADE,
)
# No get_owner_object() method
Because GymConfig does not implement get_owner_object(), WgerFormMixin catches AttributeError and sets owner_object = False, skipping any access restriction.
Security impact
This is not a cosmetic setting: GymConfig.save() performs installation-wide side effects.
File: wger/config/models/gym_config.py
def save(self, *args, **kwargs):
if self.default_gym:
UserProfile.objects.filter(gym=None).update(gym=self.default_gym)
for profile in UserProfile.objects.filter(gym=self.default_gym):
user = profile.user
if not is_any_gym_admin(user):
try:
user.gymuserconfig
except GymUserConfig.DoesNotExist:
config = GymUserConfig()
config.gym = self.default_gym
config.user = user
config.save()
return super(GymConfig, self).save(*args, **kwargs)
On deployments with multiple gyms, this allows a low-privileged user to tamper with tenant assignment defaults, affecting new registrations and bulk-updating existing users lacking a gym. This permits unauthorized modification of installation-wide state and bulk updates to other users’ records, violating the intended administrative trust boundary.
Proof of concept (local verification)
Environment: local docker compose stack, accessed via http://127.0.0.1:8088/en/.
Observed behavior
An unauthenticated user can reach the endpoint via GET; POST requires authentication and redirects to login.
An authenticated low-privileged user can submit the form and change the global singleton. After the save, the application redirects to success_url = reverse_lazy('gym:gym:list') (e.g. /en/gym/list), which is permission-protected; therefore the browser may display a “Forbidden” page even though the global update already succeeded.
DB evidence (before/after)
Before submission:
default_gym_id= None
profiles_gym_null= 1
After a low-privileged user submitted the form setting default_gym to gym id 1:
default_gym_id= 1
profiles_gym_null= 0
Recommended fix
Ensure permission enforcement runs before the form dispatch.
Using the project mixin (order matters):
class GymConfigUpdateView(WgerPermissionMixin, WgerFormMixin, UpdateView):
permission_required = 'config.change_gymconfig'
login_required = True
Alternatively, use Django’s PermissionRequiredMixin (and LoginRequiredMixin) directly.
Conclusion
The view explicitly declares permission_required = 'config.change_gymconfig', which demonstrates developer intent that this action be restricted. The fact that it is not enforced constitutes improper access control regardless of perceived business impact.

As a result, a low-privileged authenticated user can modify installation-wide configuration and trigger server-side side effects in `GymConfig.save()`.\n\nThis is a vertical privilege escalation from a regular user to privileged global configuration control.\nThe application explicitly declares permission_required = \u0027config.change_gymconfig\u0027, demonstrating that the action is intended to be restricted; however, this requirement is never enforced at runtime.\n\n## Affected endpoint\n\nThe config URLs map as follows.\n\nFile: `wger/config/urls.py`\n\n```python\npatterns_gym_config = [\n path(\u0027edit\u0027, gym_config.GymConfigUpdateView.as_view(), name=\u0027edit\u0027),\n]\n\nurlpatterns = [\n path(\n \u0027gym-config/\u0027,\n include((patterns_gym_config, \u0027gym_config\u0027), namespace=\u0027gym_config\u0027),\n ),\n]\n```\n\nThis resolves to:\n\n`/config/gym-config/edit`\n\n## Root cause\n\n### The view declares a permission but does not enforce it\n\nFile: `wger/config/views/gym_config.py`\n\n```python\nclass GymConfigUpdateView(WgerFormMixin, UpdateView):\n model = GymConfig\n fields = (\u0027default_gym\u0027,)\n permission_required = \u0027config.change_gymconfig\u0027\n success_url = reverse_lazy(\u0027gym:gym:list\u0027)\n title = gettext_lazy(\u0027Edit\u0027)\n\n def get_object(self):\n return GymConfig.objects.get(pk=1)\n```\n\nThe permission string exists, but `WgerFormMixin` does not check `permission_required`.\n\n### The project\u2019s permission mixin exists but is not used\n\nFile: `wger/utils/generic_views.py`\n\n```python\nclass WgerPermissionMixin:\n permission_required = False\n login_required = False\n\n def dispatch(self, request, *args, **kwargs):\n if self.login_required or self.permission_required:\n if not request.user.is_authenticated:\n return HttpResponseRedirect(\n reverse_lazy(\u0027core:user:login\u0027) + f\u0027?next={request.path}\u0027\n )\n\n if self.permission_required:\n has_permission = False\n if isinstance(self.permission_required, tuple):\n for permission in self.permission_required:\n if request.user.has_perm(permission):\n has_permission = True\n elif request.user.has_perm(self.permission_required):\n has_permission = True\n\n if not has_permission:\n return HttpResponseForbidden(\u0027You are not allowed to access this object\u0027)\n\n return super(WgerPermissionMixin, self).dispatch(request, *args, **kwargs)\n```\n\n`GymConfigUpdateView` does not inherit this mixin, so none of the login/permission logic runs.\n\n### The mixin that *is* used performs only ownership checks, and `GymConfig` has no owner\n\nFile: `wger/utils/generic_views.py`\n\n```python\nclass WgerFormMixin(ModelFormMixin):\n def dispatch(self, request, *args, **kwargs):\n self.kwargs = kwargs\n self.request = request\n\n if self.owner_object:\n owner_object = self.owner_object[\u0027class\u0027].objects.get(pk=kwargs[self.owner_object[\u0027pk\u0027]])\n else:\n try:\n owner_object = self.get_object().get_owner_object()\n except AttributeError:\n owner_object = False\n\n if owner_object and owner_object.user != self.request.user:\n return HttpResponseForbidden(\u0027You are not allowed to access this object\u0027)\n\n return super(WgerFormMixin, self).dispatch(request, *args, **kwargs)\n```\n\nFile: `wger/config/models/gym_config.py`\n\n```python\nclass GymConfig(models.Model):\n default_gym = models.ForeignKey(\n Gym,\n verbose_name=_(\u0027Default gym\u0027),\n # ...\n null=True,\n blank=True,\n on_delete=models.CASCADE,\n )\n # No get_owner_object() method\n```\n\nBecause `GymConfig` does not implement `get_owner_object()`, `WgerFormMixin` catches `AttributeError` and sets `owner_object = False`, skipping any access restriction.\n\n## Security impact\n\nThis is not a cosmetic setting: `GymConfig.save()` performs installation-wide side effects.\n\nFile: `wger/config/models/gym_config.py`\n\n```python\ndef save(self, *args, **kwargs):\n if self.default_gym:\n UserProfile.objects.filter(gym=None).update(gym=self.default_gym)\n\n for profile in UserProfile.objects.filter(gym=self.default_gym):\n user = profile.user\n if not is_any_gym_admin(user):\n try:\n user.gymuserconfig\n except GymUserConfig.DoesNotExist:\n config = GymUserConfig()\n config.gym = self.default_gym\n config.user = user\n config.save()\n\n return super(GymConfig, self).save(*args, **kwargs)\n```\n\nOn deployments with multiple gyms, this allows a low-privileged user to tamper with tenant assignment defaults, affecting new registrations and bulk-updating existing users lacking a gym. This permits unauthorized modification of installation-wide state and bulk updates to other users\u2019 records, violating the intended administrative trust boundary.\n\n## Proof of concept (local verification)\n\nEnvironment: local docker compose stack, accessed via `http://127.0.0.1:8088/en/`.\n\n### Observed behavior\n\nAn unauthenticated user can reach the endpoint via GET; POST requires authentication and redirects to login.\nAn authenticated low-privileged user can submit the form and change the global singleton. After the save, the application redirects to `success_url = reverse_lazy(\u0027gym:gym:list\u0027)` (e.g. `/en/gym/list`), which is permission-protected; therefore the browser may display a \u201cForbidden\u201d page even though the global update already succeeded.\n\n### DB evidence (before/after)\n\nBefore submission:\n\n```bash\ndefault_gym_id= None\nprofiles_gym_null= 1\n```\n\nAfter a low-privileged user submitted the form setting `default_gym` to gym id `1`:\n\n```bash\ndefault_gym_id= 1\nprofiles_gym_null= 0\n```\n\n## Recommended fix\n\nEnsure permission enforcement runs before the form dispatch.\n\nUsing the project mixin (order matters):\n\n```python\nclass GymConfigUpdateView(WgerPermissionMixin, WgerFormMixin, UpdateView):\n permission_required = \u0027config.change_gymconfig\u0027\n login_required = True\n```\n\nAlternatively, use Django\u2019s `PermissionRequiredMixin` (and `LoginRequiredMixin`) directly.\n\n## Conclusion \n\nThe view explicitly declares permission_required = \u0027config.change_gymconfig\u0027, which demonstrates developer intent that this action be restricted. The fact that it is not enforced constitutes improper access control regardless of perceived business impact.\n\n\u003cimg width=\"1912\" height=\"578\" alt=\"Screenshot 2026-02-27 230752\" src=\"https://github.com/user-attachments/assets/c627b404-6d9c-4477-88bd-f867d0fa09d2\" /\u003e",

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-46
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CAPEC-19: Embedding Scripts within Scripts
An adversary leverages the capability to execute their own script by embedding it within other scripts that the target software is likely to execute due to programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts.
CAPEC-441: Malicious Logic Insertion
An adversary installs or adds malicious logic (also known as malware) into a seemingly benign component of a fielded system. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. With the proliferation of mass digital storage and inexpensive multimedia devices, Bluetooth and 802.11 support, new attack vectors for spreading malware are emerging for things we once thought of as innocuous greeting cards, picture frames, or digital projectors. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems and their components that are still under development and part of the supply chain.
CAPEC-478: Modification of Windows Service Configuration
An adversary exploits a weakness in access control to modify the execution parameters of a Windows service. The goal of this attack is to execute a malicious binary in place of an existing service.
CAPEC-479: Malicious Root Certificate
An adversary exploits a weakness in authorization and installs a new root certificate on a compromised system. Certificates are commonly used for establishing secure TLS/SSL communications within a web browser. When a user attempts to browse a website that presents a certificate that is not trusted an error message will be displayed to warn the user of the security risk. Depending on the security settings, the browser may not allow the user to establish a connection to the website. Adversaries have used this technique to avoid security warnings prompting users when compromised systems connect over HTTPS to adversary controlled web servers that spoof legitimate websites in order to collect login credentials.
CAPEC-502: Intent Spoof
An adversary, through a previously installed malicious application, issues an intent directed toward a specific trusted application's component in an attempt to achieve a variety of different objectives including modification of data, information disclosure, and data injection. Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.
CAPEC-503: WebView Exposure
An adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.
CAPEC-536: Data Injected During Configuration
An attacker with access to data files and processes on a victim's system injects malicious data into critical operational data during configuration or recalibration, causing the victim's system to perform in a suboptimal manner that benefits the adversary.
CAPEC-546: Incomplete Data Deletion in a Multi-Tenant Environment
An adversary obtains unauthorized information due to insecure or incomplete data deletion in a multi-tenant environment. If a cloud provider fails to completely delete storage and data from former cloud tenants' systems/resources, once these resources are allocated to new, potentially malicious tenants, the latter can probe the provided resources for sensitive information still there.
CAPEC-550: Install New Service
When an operating system starts, it also starts programs called services or daemons. Adversaries may install a new service which will be executed at startup (on a Windows system, by modifying the registry). The service name may be disguised by using a name from a related operating system or benign software. Services are usually run with elevated privileges.
CAPEC-551: Modify Existing Service
When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.
CAPEC-552: Install Rootkit
An adversary exploits a weakness in authentication to install malware that alters the functionality and information provide by targeted operating system API calls. Often referred to as rootkits, it is often used to hide the presence of programs, files, network connections, services, drivers, and other system components.
CAPEC-556: Replace File Extension Handlers
When a file is opened, its file handler is checked to determine which program opens the file. File handlers are configuration properties of many operating systems. Applications can modify the file handler for a given file extension to call an arbitrary program when a file with the given extension is opened.
CAPEC-558: Replace Trusted Executable
An adversary exploits weaknesses in privilege management or access control to replace a trusted executable with a malicious version and enable the execution of malware when that trusted executable is called.
CAPEC-562: Modify Shared File
An adversary manipulates the files in a shared location by adding malicious programs, scripts, or exploit code to valid content. Once a user opens the shared content, the tainted content is executed.
CAPEC-563: Add Malicious File to Shared Webroot
An adversaries may add malicious content to a website through the open file share and then browse to that content with a web browser to cause the server to execute the content. The malicious content will typically run under the context and permissions of the web server process, often resulting in local system or administrative privileges depending on how the web server is configured.
CAPEC-564: Run Software at Logon
Operating system allows logon scripts to be run whenever a specific user or users logon to a system. If adversaries can access these scripts, they may insert additional code into the logon script. This code can allow them to maintain persistence or move laterally within an enclave because it is executed every time the affected user or users logon to a computer. Modifying logon scripts can effectively bypass workstation and enclave firewalls. Depending on the access configuration of the logon scripts, either local credentials or a remote administrative account may be necessary.
CAPEC-578: Disable Security Software
An adversary exploits a weakness in access control to disable security tools so that detection does not occur. This can take the form of killing processes, deleting registry keys so that tools do not start at run time, deleting log files, or other methods.
