How to fix EUVD-2026-22203?

Within 24 hours: Identify all Talend JobServer and Runtime instances and verify network exposure (scan for JMX ports, typically 7199/tcp). Within 7 days: Apply vendor-released patch Talend ESB Runtime R2024-07-RT to all affected systems, prioritizing internet-facing and externally-accessible instances. Implement network segmentation to restrict JMX port access to trusted administrative networks only. Within 30 days: Validate patch deployment across all systems, conduct post-patch vulnerability rescans, and document JMX port access controls in your network baseline.

DescriptionNVD

A critical vulnerability in the Talend JobServer and Talend Runtime allows unauthenticated remote code execution via the JMX monitoring port. The attack vector is the JMX monitoring port of the Talend JobServer. The vulnerability can be mitigated for the Talend JobServer by requiring TLS client authentication for the monitoring port; however, the patch must be applied for full mitigation. For Talend ESB Runtime, the vulnerability can be mitigated by disabling the JobServer JMX monitoring port, which is disabled by default from the R2024-07-RT patch.
