CVE-2026-2311Network attack vector

Administrator code execution via invalid authorization check

Published Apr 30, 2026 · Updated Apr 30, 2026

Privilege escalation in IBM's integrated operating system 7.2 through 7.6 allows remote authenticated users to execute code as administrators. The Web Administration GUI performs an invalid authorization check, but IBM has not disclosed the affected handler or incorrect decision logic. Exploitation requires high privileges and user interaction; success executes user-controlled code with administrator privilege.
