CVE-2026-14979Network attack vector

Service interruption via improper XML entity handling

Published Jul 17, 2026 · Updated Jul 17, 2026

XML entity expansion in IBM Engineering Lifecycle Management DOORS 7.0.3, 7.1.0, and 7.2.0 allows remote attackers to interrupt service. IBM identifies improper handling of entity expansion but does not disclose the parser, request endpoint, or failed limiting operation. No authentication or user interaction is required; processing attacker-supplied XML consumes resources and affects availability, while the published material does not identify a hang or crash.
