CVE-2026-56257 Details
Description
Capgo before 12.128.2 allows direct patching of public.apps.owner_org through PostgREST, bypassing the transfer_app() workflow and creating split-brain ownership. Attackers can directly update apps.owner_org while leaving app_versions.owner_org unchanged, enabling old-org keys to retain access to version data while new-org keys control the app record.
A vulnerability in Capgo versions prior to 12.128.2 allows users to directly update the 'public.apps.owner_org' field through PostgREST. This bypasses the intended 'transfer_app()' workflow, leading to inconsistent ownership records between the app and its versions. As a result, keys from the old organization can still access version data while the new organization controls the app record, creating a 'split-brain' ownership scenario.
Users can update to Capgo version 12.128.2 or later, where this vulnerability has been patched.
