CVE-2026-40102Public exploitNetwork attack vector

Authenticated data disclosure via unvalidated ORM field reference

Published May 20, 2026 · Updated May 20, 2026

ORM field reference injection in Plane 1.3.0 and earlier allows remote authenticated users to read related database fields via saved analytics. SavedAnalyticEndpoint passes the segment parameter without allowlist validation to build_graph_plot(), where Django F() traverses relations and .values() returns the selected field in JSON. Workspace MEMBER access is sufficient to retrieve password hashes, API tokens, and email addresses without modifying data.
