Capgo before 12.128.2 contains an authorization bypass vulnerability in webhook management endpoints that allows non-expiring API keys to bypass the require_apikey_expiration organization policy. The checkWebhookPermission function fails to call apikeyHasOrgRightWithPolicy, enabling attackers with legacy non-expiring keys to list, create, and delete webhooks despite explicit organizational policy requiring key expiration.
