CVE-2026-12542

A flaw was found in Foreman. The foreman-tail utility is vulnerable to OS command injection due to the unsafe use of the eval command. The script takes user-supplied arguments and incorporates them directly into a string that is then executed by eval to expand file paths. Because the input is not sanitized or quoted, a local attacker can inject shell metacharacters (e.g., ;, &, |) to execute arbitrary system commands.
