Title
REVA Public Link Exploit
Summary
REVA is an interoperability platform. Prior to 2.42.3 and 2.40.3, a bug in the GRPC authorization middleware of the "Reva" component of OpenCloud allows a malicious user to bypass the scope verification of a public link. By exploiting this via the the "archiver" service this can be leveraged to create an archive (zip or tar-file) containing all resources that this creator of the public link has access to. This vulnerability is fixed in 2.42.3 and 2.40.3.

Title
Apache Superset: SQLLab Read-Only Bypass on PostgreSQL
Summary
An Improper Input Validation vulnerability exists in Apache Superset that allows an authenticated user with SQLLab access to bypass the read-only verification check when using a PostgreSQL database connection.
While the system effectively blocks standard Data Manipulation Language (DML) statements (e.g., INSERT, UPDATE, DELETE) on read-only connections, it fails to detect them in specially crafted SQL statements.
This issue affects Apache Superset: before 6.0.0.
Users are recommended to upgrade to version 6.0.0, which fixes the issue.

Title
Apache Superset: Improper Authorization in Dataset Creation Allows Access Control Bypass
Summary
An Improper Authorization vulnerability exists in Apache Superset that allows a low-privileged user to bypass data access controls. When creating a dataset, Superset enforces permission checks to prevent users from querying unauthorized data. However, an authenticated attacker with permissions to write datasets and read charts can bypass these checks by overwriting the SQL query of an existing dataset.
This issue affects Apache Superset: before 6.0.0.
Users are recommended to upgrade to version 6.0.0, which fixes the issue.

Title
Mastodon has insufficient access control to push notification settings
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.5.5, 4.4.12, and 4.3.18, an insecure direct object reference in the web push subscription update endpoint lets any authenticated user update another user's push subscription by guessing or obtaining the numeric subscription id. This can be used to disrupt push notifications for other users and also leaks the web push subscription endpoint. Any user with a web push subscription is impacted, because another authenticated user can tamper with their push subscription settings if they can guess or obtain the subscription id. This allows an attacker to disrupt push notifications by changing the policy (whether to filter notifications from non-followers or non-followed users) and subscribed notification types of their victims. Additionally, the endpoint returns the subscription object, which includes the push notification endpoint for this subscription, but not its keypair. Mastodon versions v4.5.5, v4.4.12, v4.3.18 are patched.

Title
Mastodon may allow a remote suspension bypass
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Mastodon allows server administrators to suspend remote users to prevent interactions. However, some logic errors allow already-known posts from such suspended users to appear in timelines if boosted. Furthermore, under certain circumstances, previously-unknown posts from suspended users can be processed. This issue allows old posts from suspended users to occasionally end up on timelines on all Mastodon versions. Additionally, on Mastodon versions from v4.5.0 to v4.5.4, v4.4.5 to v4.4.11, v4.3.13 to v4.3.17, and v4.2.26 to v4.2.29, remote suspended users can partially bypass the suspension to get new posts in. Mastodon versions v4.5.5, v4.4.12, v4.3.18 are patched.

Title
Unauthorized host creation via configuration.import API by low-privilege user with write permissions
Summary
An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by creating unauthorized hosts. Note that the User role is normally not sufficient to create and edit templates/hosts even with write permissions.

Title
MyTube has an Authorization Bypass vulnerability
Summary
MyTube is a self-hosted downloader and player for several video websites. A vulnerability present in version 1.7.65 and poetntially earlier versions allows unauthenticated users to bypass the mandatory authentication check in the roleBasedAuthMiddleware. By simply not providing an authentication cookie (making req.user undefined), a request is incorrectly passed through to downstream handlers. All users running MyTube with loginEnabled: true are impacted. This flaw allows an attacker to access and modify application settings via /api/settings, change administrative and visitor passwords, and access other protected routes that rely on this specific middleware. The problem is patched in v1.7.66. MyTube maintainers recommend all users upgrade to at least version v1.7.64 immediately to secure their instances. The fix ensures that the middleware explicitly blocks requests if a user is not authenticated, rather than defaulting to next(). Those who cannot upgrade immediately can mitigate risk by restricting network access by usi a firewall or reverse proxy (like Nginx) to restrict access to the /api/ endpoints to trusted IP addresses only or, if they are comfortable editing the source code, manually patch by locating roleBasedAuthMiddleware and ensuring that the logic defaults to an error (401 Unauthorized) when req.user is undefined, instead of calling next().

"value": "MyTube is a self-hosted downloader and player for several video websites. A vulnerability present in version 1.7.65 and poetntially earlier versions allows unauthenticated users to bypass the mandatory authentication check in the roleBasedAuthMiddleware. By simply not providing an authentication cookie (making req.user undefined), a request is incorrectly passed through to downstream handlers. All users running MyTube with loginEnabled: true are impacted. This flaw allows an attacker to access and modify application settings via /api/settings, change administrative and visitor passwords, and access other protected routes that rely on this specific middleware. The problem is patched in v1.7.66. MyTube maintainers recommend all users upgrade to at least version v1.7.64 immediately to secure their instances. The fix ensures that the middleware explicitly blocks requests if a user is not authenticated, rather than defaulting to next(). Those who cannot upgrade immediately can mitigate risk by restricting network access by usi a firewall or reverse proxy (like Nginx) to restrict access to the /api/ endpoints to trusted IP addresses only or, if they are comfortable editing the source code, manually patch by locating roleBasedAuthMiddleware and ensuring that the logic defaults to an error (401 Unauthorized) when req.user is undefined, instead of calling next()."

Title
Gogs user can update repository content with read-only permission
Summary
Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, the endpoint "PUT /repos/:owner/:repo/contents/*" does not require write permissions and allows access with read permission only via repoAssignment(). After passing the permission check, PutContents() invokes UpdateRepoFile(), which results in commit creation and the execution of git push. As a result, a token with read-only permission can be used to modify repository contents. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

Title
Improper Access Control in TeamViewer clients
Summary
Improper access control in the TeamViewer Full and Host clients (Windows, macOS, Linux) prior version 15.74.5 allows an authenticated user to bypass additional access controls with “Allow after confirmation” configuration in a remote session. An exploit could result in unauthorized access prior to local confirmation. The user needs to be authenticated for the remote session via ID/password, Session Link, or Easy Access as a prerequisite to exploit this vulnerability.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
No CAPEC attack patterns related to this CWE.
