CVE-2026-5935Network attack vector

Unauthenticated command execution via HTTP endpoint

Published Apr 22, 2026 · Updated Apr 22, 2026

OS command injection in IBM TSSC/IMC 9.2 through 9.6 allows remote attackers to execute commands as a normal user via HTTP or HTTPS. IBM attributes the flaw to improper validation of user-supplied input at an HTTP/HTTPS endpoint but does not identify the handler, parameter, or command construction operation. No authentication or user interaction is required; successful exploitation grants normal-user command execution with bounded confidentiality, integrity, and availability impact.
