CVE-2026-96119: IBM i code injection in HTTP Server Administration

CVE-2026-96119 · Severity: critical · CVSS 9.9 · Published 2026-10-13

IBM i is an enterprise operating system that runs critical business applications on IBM Power Systems. A remote authenticated attacker can exploit improper input validation in the HTTP Server Administration web console to inject and execute arbitrary code on the system, achieving complete system compromise. This vulnerability allows attackers who have any valid credentials to bypass security controls and take over the entire server.

Technical details

The HTTP Server Administration GUI in IBM i fails to properly sanitize user input, allowing code injection (CWE-94). A remote authenticated attacker can exploit this to execute arbitrary code with full system impact including confidentiality, integrity, and availability compromise across connected systems. The vulnerability requires valid credentials (PR:L) but no user interaction (UI:N) and operates over the network.
