# Talend JobServer

This release provides critical security improvements and execution stability fixes to Talend JobServer, addressing JMX security vulnerabilities, Job failure handling, and process reliability.

## Critical fixes

| Issue | Description |
| --- | --- |
| DPE-2256 | Implemented JMX request filtering to prevent remote creation of JMX MBeans.<br>Remote access is now restricted to read-only information for specific JobServer<br>MBeans. For details, see the [critical security fix notice](https://community.qlik.com/t5/Official-Support-Articles/Critical-Security-fix-for-the-Qlik-Talend-JobServer-and-Talend/ta-p/2541970). |
| DPE-2030 | Fixed a corner case where Job failure conflicts with cache cleanup,<br>preventing execution retries from identifying the required JVM. The JobServer now<br>automatically detects when redeploy is needed. |
