CVE-2026-6264
Critical Security fix for the Talend JobServer and Talend Runtime
Description
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.
