CVE-2025-36049Network attack vector

Authenticated command execution via serial XML transformation

Published Jun 18, 2025 · Updated Aug 24, 2025

XXE in IBM webMethods Integration Server pub.xslt.transformSerialXML 10.5, 10.7, 10.11, and 10.15 allows remote authenticated users to run commands. The service processes attacker-supplied XML without restricting external entity resolution, allowing the transformation path to reach command execution. Exploitation requires authenticated network access to the service and runs commands in the server process context.
