Weblate is a web based localization tool. Prior to version 5.16.1, the REST API's AddonViewSet (weblate/api/views.py, line 2831) uses queryset = Addon.objects.all() without overriding get_queryset() to scope results by user permissions. This allows any authenticated user (or anonymous users if REQUIRE_LOGIN is not set) to list and retrieve ALL addons across all projects and components via GET /api/addons/ and GET /api/addons/{id}/. Version 5.16.1 fixes the issue.
AnalysisAI
Weblate versions prior to 5.16.1 fail to properly restrict API access to addon data, allowing authenticated users to enumerate and access all addons across every project and component in the system. An attacker with valid credentials can query the REST API endpoints to retrieve sensitive addon information that should be scoped to their assigned permissions. This information disclosure vulnerability is fixed in version 5.16.1.
Technical ContextAI
Classified as CWE-200 (Information Exposure). Affects Weblate. Weblate is a web based localization tool. Prior to version 5.16.1, the REST API's AddonViewSet (weblate/api/views.py, line 2831) uses queryset = Addon.objects.all() without overriding get_queryset() to scope results by user permissions. This allows any authenticated user (or anonymous users if REQUIRE_LOGIN is not set) to list and retrieve ALL addons across all projects and components via GET /api/addons/ and GET /api/addons/{id}/. Version 5.16.1 fixes the issue.
