CVE-2026-6264

CVE-2026-6264 is a critical remote code execution vulnerability affecting Talend JobServer and Talend Runtime that exploits the JMX monitoring port to enable unauthenticated attacks. This vulnerability poses significant risk to organizations running affected Talend products as an entry point for unauthorized system compromise. The vulnerability presents a network-based attack vector with low complexity and no authentication requirements, resulting in a critical CVSS score of 9.8. Successful exploitation grants attackers complete system access with high impact across confidentiality, integrity, and availability. TLS client authentication can provide temporary mitigation for JobServer; however, official patches are required for comprehensive protection. No active exploitation has been documented at this time, as the vulnerability is not included on the CISA KEV catalog and remains inactive on the Hot List. The EPSS score of 0.00097 indicates relatively low predicted likelihood of real-world exploitation compared to the broader CVE population, suggesting this remains primarily a theoretical threat despite its critical severity rating.
