CVE-2026-6264
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.

Unauthenticated remote code execution in Talend JobServer and Runtime via JMX port; patch available.
Vulnerability
CVE-2026-6264 is a critical vulnerability in the Talend JobServer and Talend Runtime that allows unauthenticated remote code execution. The root cause is that the JMX monitoring port does not require authentication, enabling an attacker to send malicious payloads [1].
Exploitation
The attack vector is the JMX monitoring port of the Talend JobServer, accessible over the network without any authentication or user interaction. An attacker with network access to this port can exploit the vulnerability to execute arbitrary code [1].
Impact
Successful exploitation grants the attacker full remote code execution on the affected server, leading to complete compromise of confidentiality, integrity, and availability. The CVSS v3.1 score is 9.8 (Critical) [1].
Mitigation
For Talend JobServer, mitigation requires enabling TLS client authentication on the monitoring port and applying the patch (TPS-6017 for 8.0, TPS-6018 for 7.3). For Talend Runtime, the JMX port is disabled by default from R2024-07-RT; upgrading to 8.0.1.R2026-01-RT or 7.3.1-R2026-01 fully resolves the issue [1].
