CVE-2026-27457
February 26, 2026
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.
