CVE-2026-13107Network attack vector

Authenticated data disclosure via default external entities

Published Sep 14, 2026 · Updated Sep 14, 2026

XML external entity injection in affected IBM Business Automation Workflow releases allows remote authenticated users to read data or consume memory. Advanced custom applications use programming-model artifacts that permit external entity resolution by default; IBM has not identified the specific artifact or parser. Exploitation requires an authenticated network user to submit attacker-controlled XML through an affected custom application, exposing sensitive data or reducing service availability.
