CVE-2026-84675Network attack vectorHinoki check available

Agent command execution via unescaped environment variables

Published Sep 2, 2026 · Updated Sep 2, 2026

OS command injection in Jenkins TICS Plugin 2025.1.1 and earlier allows attackers to execute arbitrary commands on build agents. The Run TICS build step inserts attacker-controlled build environment variable values into its operating-system command without correctly escaping shell-significant characters. The attacker must control environment-variable values consumed by a TICS build; commands run with the build agent process's privileges.
