CVE-2023-32327Network attack vector

Data exposure and memory exhaustion via XXE

Published Feb 3, 2024 · Updated Nov 3, 2025

XXE injection in IBM Security Verify Access 10.0.0.0 through 10.0.6.1 allows remote authenticated users to read sensitive data. An XML parser processing attacker-supplied XML permits external entity resolution, enabling entity-content retrieval or expansion-driven memory consumption. IBM has not identified the affected XML endpoint or parser; network access and a low-privilege authenticated session are required, and the bounded effects are data exposure and service degradation.
