CVE-2026-6264Network attack vector

Unauthenticated code execution via JMX monitoring

Published Apr 14, 2026 · Updated Apr 14, 2026

Remote code execution in Talend JobServer and Talend Runtime allows remote attackers to execute code through the JMX monitoring port. Qlik has not disclosed which JMX operation or input-validation failure permits code execution. Exploitation requires a reachable monitoring port without client authentication; recent Runtime 8.0 patches disable that port by default.
