Technical details

Weblate is vulnerable to Insecure Direct Object Reference (IDOR) and broken authorization within its REST API. The flaw allows an authenticated attacker with low privileges to bypass intended access controls to list all registered users and retrieve individual user notification settings. This systematic enumeration is caused by improper authorization checks (CWE-285) when accessing specific API endpoints. The vulnerability is addressed in Weblate version 5.15.
