CVE-2026-55227

Observable object existence disclosure in private Weblate projects via globally scoped object lookups

Published Aug 26, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
Description
Weblate is a web-based localization tool. In versions prior to 2026.7, several endpoints look up objects in a globally scoped manner rather than restricting the lookup to projects the user can access, so they return HTTP 403 (Forbidden) instead of 404 (Not Found) when a user requests an object they are not authorized to see. This difference lets unauthorized users infer whether a given object exists in a private Weblate project. The issue has been fixed in version 2026.7.
