CVE-2026-27705Network attack vector

Cross-workspace asset modification via unscoped UUID lookup

Published Feb 25, 2026 · Updated Feb 25, 2026

IDOR in Plane before 1.2.2 allows remote authenticated users to modify asset metadata across workspaces via crafted asset UUIDs. ProjectAssetEndpoint.patch() loads FileAsset records globally by pk instead of constraining the query to the workspace and project in the URL. Even GUEST-role access is sufficient to alter attributes and mark another tenant's asset as uploaded, corrupting metadata without reading file contents.
