Description
Kubero through 3.1.1 fails to apply authentication guards to the notifications API endpoints, allowing unauthenticated attackers to read webhook secrets and service URLs. Attackers can retrieve stored credentials and register malicious webhooks to intercept pipeline events or suppress alerting by deleting existing configurations.
