Improper Access Control (IDOR) in the Graylog API, version 2.2.3, which occurs when modifying the user ID in the URL. An authenticated user can access other user's profiles without proper authorization checks. Exploiting this vulnerability allows valid users of the system to be listed and sensitive third-party information to be accessed, such as names, email addresses, internal identifiers, and last activity. The endpoint 'http://<IP>:12900/users/<my_user>' does not implement object-level authorization validations.

Improper access control in secure message component in Devolutions Server allows an authenticated user to steal unauthorized entries via the secure message entry attachment feature This issue affects the following versions : * Devolutions Server 2025.2.2.0 through 2025.2.4.0 * Devolutions Server 2025.1.11.0 and earlier

The CGM CLININET application uses direct, sequential object identifiers "MessageID" without proper authorization checks. By modifying the parameter in the GET request, an attacker can access messages and attachments belonging to other users.

Misskey is an open source, federated social media platform. Starting in version 13.0.0-beta.16 and prior to version 2025.12.0, an actor who does not have permission to view favorites or clips can can export the posts and view the contents. Version 2025.12.0 fixes the issue.

LinkAce is a self-hosted archive to collect website links. In versions 2.3.1 and below, authenticated RSS feed endpoints in the FeedController class fail to implement proper authorization checks, allowing any authenticated user to access all links, lists, and tags from all users in the system, regardless of their ownership or visibility settings. This issue is fixed in version 2.4.0.

LinkAce is a self-hosted archive to collect website links. Versions 2.3.1 and below allow any authenticated user to export the entire database of links from all users in the system, including private links that should only be accessible to their owners. The HTML and CSV export functions in the ExportController class retrieve all links without applying any ownership or visibility filtering, effectively bypassing all access controls implemented elsewhere in the application. This issue is fixed in version 2.4.0.

External Secrets Operator is a Kubernetes operator that integrates external secret management systems. From version 0.15.0 to before 0.19.2, a vulnerability was discovered where the List() calls for Kubernetes Secret and SecretStore resources performed by the PushSecret controller did not apply a namespace selector. This flaw allowed an attacker to use label selectors to list and read secrets/secret-stores across the cluster, bypassing intended namespace restrictions. An attacker with the ability to create or update PushSecret resources and control SecretStore configurations could exploit this vulnerability to exfiltrate sensitive data from arbitrary namespaces. This could lead to full disclosure of Kubernetes secrets, including credentials, tokens, and other sensitive information stored in the cluster. This vulnerability has been patched in version 0.19.2. A workaround for this issue includes auditing and restricting RBAC permissions so that only trusted service accounts can create or update PushSecret and SecretStore resources.

ProjectSend r1605 contains an insecure direct object reference vulnerability that allows unauthenticated attackers to download private files by manipulating the download ID parameter. Attackers can access any user's private files by changing the 'id' parameter in the download request to process.php.
