Severity: low Affected versions:
- Apache TomEE (org.apache.tomee:tomee-security) 10.0.0-M2 before 10.3.0 - Apache TomEE (org.apache.tomee:tomee-security) 11.0.0-M1 before 11.0.0-M2 Description: The Jakarta Security OpenID Connect authentication mechanism generates the state and nonce values with a non-cryptographic random number generator and insufficient entropy. A remote attacker who predicts these values can forge an authentication callback that logs a victim into the attacker's account, and the replay protection for ID tokens is weakened. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
