Authentication Bypass in Jakarta Security OpenID Connect

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: Apache Software Foundation

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.

Executive Summary

This vulnerability involves the Jakarta Security OpenID Connect authentication mechanism using a weak random number generator to create state and nonce values. These values lack sufficient entropy, making them predictable. An attacker who can guess these values could forge an authentication callback, tricking the system into logging a victim into the attacker's account. Additionally, the replay protection for ID tokens is weakened.

Impact Analysis

If exploited, this vulnerability could allow an attacker to gain unauthorized access to your account by predicting authentication tokens. This could lead to data theft, account takeover, or other malicious activities depending on the application's use of OpenID Connect.
