Vulnerability in Capgo
CVE-2026-56334
Capgo before 12.128.2 lacks an UPDATE row-level security policy for the build_requests table, preventing API-key and anonymous access from persisting builder status updates. Attackers can exploit this missing policy to cause build status and error details to remain unpersisted, leaving build_requests rows stuck in pending state with null last_error values.
