Cross-project event disclosure via unscoped UUID lookup
Published May 26, 2026 · Updated May 26, 2026
Authorization bypass in Bugsink before 2.2.0 allows remote authenticated users to view event data from other projects via issue event URLs. The stacktrace, details, and breadcrumbs views resolve a URL-supplied event UUID without verifying that the event belongs to the authorized issue and project. Exploitation requires access to one project and prior knowledge of a valid event UUID; it exposes event data but does not cross hosted tenant boundaries.
