CVE-2026-41449

Command execution via unescaped placeholders passed to eval

Published Aug 21, 2026 · Updated Aug 21, 2026

Command injection in Unix-like Artifacts Collector before 3.3.0 allows attackers to execute commands on an analyst host via crafted evidence. The _run_command function passes artifact commands containing %user%, %user_home%, or %line% substitutions to eval without shell-context escaping, causing metacharacters to be interpreted by the shell. Execution requires an analyst to process a hostile live system, mounted image, or tampered artifact definition, and injected commands inherit the UAC process's privileges.
