CVE-2026-14277

Command execution via unchecked session-file Run action

Published Sep 14, 2026 · Updated Sep 14, 2026

Command injection in Access Client Solutions 1.1.2.0 through 1.1.9.15 allows local operators to execute arbitrary commands. The 5250 multiple-session file handler accepts a crafted .bch or .bchx file and executes the embedded Run action without confirmation. Opening the session file after authentication is required, and commands run with normal account privileges.
