# Jakarta Security OpenID Connect: predictable state and nonce allow forged login callbacks

Link for people: https://infrastack.ai/live/CVE-2026-111260 (this .md is for agents)

The Jakarta Security OpenID Connect authentication mechanism generates its state and nonce values with a non-cryptographic random number generator and too little entropy. A remote attacker who predicts these values can forge an authentication callback that logs a victim into the attacker's account, and ID token replay protection is weakened.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Jakarta Security OpenID Connect dependency version in the project build file (for example `pom.xml` or `build.gradle`) and see whether it is below `10.3.0` or `11.0.0-M2`
- Confirm whether the application uses the Jakarta Security OpenID Connect authentication mechanism for login

## Fix

- Upgrade to `10.3.0` or `11.0.0-M2`, which the sources state fix the issue

## Timeline

## From the sources

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.
