CVE-2026-11864Network attack vector

Sensitive data disclosure via XPath injection

Published Sep 15, 2026 · Updated Sep 15, 2026

XPath injection in IBM Cloud Pak for Business Automation Process Federation Server allows remote authenticated users to read sensitive data. IBM has not disclosed the affected endpoint, XPath expression, or the operation that incorporates attacker-controlled input into that expression. A valid application account and network access to the Process Federation Server REST service are required; exploitation discloses application data or reveals the XML document structure without changing data or interrupting service.
