{"id":"CVE-2026-27457","state":"PUBLISHED","title":"Weblate: Missing access control for the AddonViewSet API exposes all addon configurations","description":"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.","publishedAt":"2026-02-26T21:56:03.220Z","updatedAt":"2026-03-03T01:39:37.771Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["WeblateOrg weblate"],"affected":[{"vendor":"WeblateOrg","product":"weblate","versions":[{"version":"< 5.16.1","status":"affected"}]}],"references":["https://github.com/WeblateOrg/weblate/security/advisories/GHSA-wppc-7cq7-cgfv","https://github.com/WeblateOrg/weblate/pull/18107","https://github.com/WeblateOrg/weblate/pull/18164","https://github.com/WeblateOrg/weblate/commit/3f58f9a4152bc0cbdd6eff5954f9c7bc4d9f0af9","https://github.com/WeblateOrg/weblate/commit/7802c9b121eb407c48d4adddd4f2458fb3efef0f","https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.16.1"],"weaknesses":["CWE-862","CWE-200"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27457.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27457","state":"PUBLISHED","datePublished":"2026-02-26T21:56:03.220Z","dateUpdated":"2026-03-03T01:39:37.771Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-19T17:25:31.100Z"},"containers":{"cna":{"title":"Weblate: Missing access control for the AddonViewSet API exposes all addon configurations","descriptions":[{"lang":"en","value":"Weblate is a web based localization tool.
