Vulnerability in Capgo
CVE-2026-56217
Capgo before 12.128.2 contains a policy bypass vulnerability in app_versions update enforcement that allows app-scoped API keys to downgrade encrypted bundles to non-encrypted state. Attackers with app-scoped all API keys can directly update the app_versions table via PostgREST to clear session_key and key_id fields, bypassing organization-enforced encrypted-bundle policies and weakening OTA security controls.
