CVE-2026-3603Network attack vector

Authenticated data exposure via XML external entities

Published May 26, 2026 · Updated May 26, 2026

XXE in Jazz Foundation in IBM Engineering Lifecycle Management 7.0.3, 7.1.0, and 7.2.0 allows remote authenticated users to expose sensitive data. IBM states that Jazz Foundation processes attacker-supplied XML with external entities but has not disclosed the affected parser, endpoint, or unsafe code operation. Authenticated network access is required; exploitation can disclose data or consume memory resources, reducing service availability.
