CVE-2026-47728Network attack vector

Cross-project source disclosure via globally resolved debug IDs

Published May 26, 2026 · Updated May 26, 2026

Missing authorization in Bugsink before 2.2.0 allows remote authenticated users to disclose cross-project source context via debug IDs. Sourcemap and debug-file lookup resolves client-supplied debug IDs globally instead of requiring metadata to belong to the event's project. Access to one project and a matching debug ID are required; debug-file exposure also requires experimental FEATURE_MINIDUMPS, and hosted tenants remain isolated.
