CVE-2026-56257

Capgo - Authorization Bypass in App Ownership Transfer via Direct PostgREST Update

State: Published
Severity: 7.1 High
Published: Jun 24, 2026
Updated: Jun 25, 2026
Reserved: Jun 19, 2026

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.
