    Title
    Kubero 3.0.0 through 3.1.1 Authentication Bypass via Hardcoded JWT Secret
    Summary
    Kubero 3.0.0 through 3.1.1 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to forge administrative JWTs by using a hardcoded fallback signing secret when JWT_SECRET is unset. Attackers can sign tokens with arbitrary role, userGroups and permissions claims, which JwtStrategy.validate() trusts without a database lookup, to take control of pipelines, applications, users and API tokens.

    Summary
    Kubero 3.0.0 through 3.1.1 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to forge administrative JWTs by using a hardcoded fallback signing secret when JWT_SECRET is unset. Attackers can sign tokens with arbitrary role, userGroups and permissions claims, which JwtStrategy.validate() trusts without a database lookup, to take control of pipelines, applications, users and API tokens.

    Title
    Kubero through 3.1.1 Unauthenticated Notifications API Access
    Summary
    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.
