Codechecker has an authentication bypass for certain API calls
Summary
Authentication bypass occurs when the URL ends with Authentication with certain function calls. This bypass allows assigning arbitrary permissions to any existing user in CodeChecker.
Details
The following functions are affected under the Authentication endpoint: getAuthorisedNames, getPermissionsForUser, hasPermission, addPermission, and removePermission.
The vulnerability allows unauthenticated users to execute these function calls with arbitrary arguments. In the logs, the exploit shows as follows:
Impact
An attacker with a CodeChecker user can effectively acquire superuser permissions by calling these endpoints.

A patch is available at https://github.com/Ericsson/codechecker/releases/tag/v6.27.4.
