CWE-915

Allowed

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Abstraction: Base · Status: Incomplete

The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified.

314 vulnerabilities reference this CWE, most recent first.

CVE-2026-32640 (GCVE-0-2026-32640)

Title
(SimpleEval) Objects (including modules) can leak dangerous modules through to direct access inside the sandbox.
Summary
SimpleEval is a library for adding evaluatable expressions into python projects. Prior to 1.0.5, objects (including modules) can leak dangerous modules through to direct access inside the sandbox. If the objects you've passed in as names to SimpleEval have modules or other disallowed / dangerous objects available as attrs. Additionally, dangerous functions or modules could be accessed by passing them as callbacks to other safe functions to call. The latest version 1.0.5 has this issue fixed. This vulnerability is fixed in 1.0.5.

Title
django-unicorn affected by component state manipulation via unvalidated attribute access
Summary
Unicorn adds modern reactive component functionality to your Django templates. Prior to 0.67.0, component state manipulation is possible in django-unicorn due to missing access control checks during property updates and method calls. An attacker can bypass the intended _is_public protection to modify internal attributes such as template_name or trigger protected methods. This vulnerability is fixed in 0.67.0.

Title
Kanboard's privilege escalation via mass assignment in user invite registration allows any invited user to become admin
Summary
Kanboard is project management software focused on Kanban methodology. Prior to 1.2.51, Kanboard's user invite registration endpoint (`UserInviteController::register()`) accepts all POST parameters and passes them to `UserModel::create()` without filtering out the `role` field. An attacker who receives an invite link can inject `role=app-admin` in the registration form to create an administrator account. Version 1.2.51 fixes the issue.

CVE-2026-28781 (GCVE-0-2026-28781)

Vulnerability from cvelistv5 – Published: 2026-03-04 16:31 – Updated: 2026-03-04 17:36

Title
Craft Affected by Entries Authorship Spoofing via Mass Assignment
Summary
Craft is a content management system (CMS). Prior to 4.17.0-beta.1 and 5.9.0-beta.1, the entry creation process allows for Mass Assignment of the authorId attribute. A user with "Create Entries" permission can inject the authorIds[] (or authorId) parameter into the POST request, which the backend processes without verifying if the current user is authorized to assign authorship to others. Normally, this field is not present in the request for users without the necessary permissions. By manually adding this parameter, an attacker can attribute the new entry to any user, including Admins. This effectively "spoofs" the authorship. This vulnerability is fixed in 4.17.0-beta.1 and 5.9.0-beta.1.

Title
Privilege Escalation via Mass Assignment Allows Regular Users to Set Topics as Global Banners
Summary
Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, an improper authorization check in the topic management logic allows authenticated users to modify privileged attributes of their topics. By manipulating specific parameters in a PUT or POST request, a regular user can elevate a topic’s status to a site-wide notice or banner, bypassing intended administrative restrictions. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. There are no practical workarounds to prevent this behavior other than applying the security patch. Administrators concerned about unauthorized promotions should audit recent changes to site banners and global notices until the fix is deployed.

CVE-2026-27953 (GCVE-0-2026-27953)

Title
ormar has a Pydantic Validation Bypass via Kwargs Injection in Model Constructor
Summary
ormar is a async mini ORM for Python. Versions 0.23.0 and below are vulnerable to Pydantic validation bypass through the model constructor, allowing any unauthenticated user to skip all field validation by injecting "__pk_only__": true into a JSON request body. By injecting "__pk_only__": true into a JSON request body, an unauthenticated attacker can skip all field validation and persist unvalidated data directly to the database. A secondary __excluded__ parameter injection uses the same pattern to selectively nullify arbitrary model fields (e.g., email or role) during construction. This affects ormar's canonical FastAPI integration pattern recommended in its official documentation, enabling privilege escalation, data integrity violations, and business logic bypass in any application using ormar.Model directly as a request body parameter. This issue has been fixed in version 0.23.1.

A secondary __excluded__ parameter injection uses the same pattern to selectively nullify arbitrary model fields (e.g., email or role) during construction.

CVE-2026-27591 (GCVE-0-2026-27591)

Vulnerability from cvelistv5 – Published: 2026-03-11 21:25 – Updated: 2026-03-12 14:23

Title
Winter: Privilege escalation by authenticated backend users
Summary
Winter is a free, open-source content management system (CMS) based on the Laravel PHP framework. Prior to 1.0.477, 1.1.12, and 1.2.12, Winter CMS allowed authenticated backend users to escalate their accounts level of access to the system by modifying the roles / permissions assigned to their account through specially crafted requests to the backend while logged in. To actively exploit this security issue, an attacker would need access to the Backend with a user account with any level of access. This vulnerability is fixed in 1.0.477, 1.1.12, and 1.2.12.

CVE-2026-27125 (GCVE-0-2026-27125)

Vulnerability from cvelistv5 – Published: 2026-02-20 22:29 – Updated: 2026-02-25 21:33

Title
Svelte SSR attribute spreading includes inherited properties from prototype chain
Summary
svelte performance oriented web framework. Prior to 5.51.5, in server-side rendering, attribute spreading on elements (e.g. <div {...attrs}>) enumerates inherited properties from the object's prototype chain rather than only own properties. In environments where Object.prototype has already been polluted — a precondition outside of Svelte's control — this can cause unexpected attributes to appear in SSR output or cause SSR to throw errors. Client-side rendering is not affected. This vulnerability is fixed in 5.51.5.

CVE-2026-24140 (GCVE-0-2026-24140)

Vulnerability from cvelistv5 – Published: 2026-01-23 23:59 – Updated: 2026-01-26 16:17
VLAI
Title
MyTube has Mass Assignment via Settings Management
Summary
MyTube is a self-hosted downloader and player for several video websites. Versions 1.7.78 and below have a Mass Assignment vulnerability in the settings management functionality due to insufficient input validation. The application's saveSettings() function accepts arbitrary key-value pairs without validating property names against allowed settings. The function uses Record<string, any> as input type and iterates over all entries using Object.entries() without filtering unauthorized properties. Any field sent by the attacker is directly persisted to the database, regardless of whether it corresponds to a legitimate application setting. This issue has been fixed in version 1.7.78.

Mitigation
Implementation
  • If available, use features of the language or framework that allow specification of allowlists of attributes or fields that are allowed to be modified. If possible, prefer allowlists over denylists.
  • For applications written with Ruby on Rails, use the attr_accessible (allowlist) or attr_protected (denylist) macros in each class that may be used in mass assignment.
Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

Strategy: Input Validation

For any externally-influenced input, check the input against an allowlist of internal object attributes or fields that are allowed to be modified.

Mitigation
Implementation Architecture and Design

Strategy: Refactoring

Refactor the code so that object attributes or fields do not need to be dynamically identified, and only expose getter/setter functionality for the intended attributes.
