CVE-2026-56079

Capgo before 12.128.2 contains a cross-tenant authorization bypass vulnerability in PostgREST endpoints that allows org-scoped read API keys to access other tenants' webhook secrets and delivery logs. Attackers can query the webhooks and webhook_deliveries endpoints to exfiltrate HMAC signing secrets and delivery payloads, enabling forged webhook events against victim organizations.
