CVE-2026-65013Public exploitNetwork attack vector

Cross-tenant data access and manipulation via unchecked identifiers

Published Jul 22, 2026 · Updated Jul 22, 2026

Broken object authorization in Onlook 0.2.32 and earlier allows remote authenticated users to read, modify, or delete other users' data. Numerous tRPC procedures trust client-supplied resource UUIDs without verifying that the caller belongs to the owning project, while the database connection bypasses row-level security. Any account can target another user's known project or conversation identifier, exposing project details and permitting membership or conversation changes.
