{"cve":"CVE-2026-27457","nvd":{"published":"2026-02-26T22:20:48.133","modified":"2026-06-17T10:27:11.127","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-862","CWE-200"],"references":["https://github.com/WeblateOrg/weblate/commit/3f58f9a4152bc0cbdd6eff5954f9c7bc4d9f0af9","https://github.com/WeblateOrg/weblate/commit/7802c9b121eb407c48d4adddd4f2458fb3efef0f","https://github.com/WeblateOrg/weblate/pull/18107","https://github.com/WeblateOrg/weblate/pull/18164","https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.16.1"],"products":["weblate:weblate"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27457","score":0.00348,"percentile":0.2843,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wppc-7cq7-cgfv","url":"https://osv.dev/vulnerability/GHSA-wppc-7cq7-cgfv","summary":"Weblate: Missing access control for the AddonViewSet API exposes all addon configurations","modified":"2026-07-13T07:26:38.986681277Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<5.16.1"],"fixed":["5.16.1"]}]},{"id":"PYSEC-2026-2310","url":"https://osv.dev/vulnerability/PYSEC-2026-2310","summary":"","modified":"2026-07-13T07:15:47.892235811Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<5.16.1"],"fixed":["5.16.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
