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.","published_at":"2026-02-26T21:56:03.220000Z","last_modified_at":null,"cvss_v3_score":4.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-862","CWE-200"],"nvd_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"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:32.155599Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"weblateorg","vendor_name":"WeblateOrg","product_slug":"weblate","product_name":"weblate","version_start":"< 5.16.1","version_start_inclusive":true,"version_end":"< 5.16.1","version_end_inclusive":true,"cpe23_uri":"cve5:weblateorg:weblate:< 5.16.1:< 5.16.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-wppc-7cq7-cgfv","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/WeblateOrg/weblate/pull/18107","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/pull/18164","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/commit/3f58f9a4152bc0cbdd6eff5954f9c7bc4d9f0af9","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/commit/7802c9b121eb407c48d4adddd4f2458fb3efef0f","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.16.1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-26T21:56:03.220000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"}]}
