CVE-2026-27457

Description

Weblate is a web based localization tool. Prior to version 5.16.1, the REST APIs 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.
