Description
CVE-2026-56295 is an authorization bypass vulnerability in Capgo versions before 12.128.2. It affects webhook management endpoints by allowing legacy non-expiring API keys to bypass an organizational policy that requires API key expiration. This occurs because the function responsible for checking webhook permissions does not properly enforce the expiration policy, enabling unauthorized listing, creation, and deletion of webhooks.
