Foreman: command injection in foreman-tail

Summary

CVE	CVE-2026-12542
State	PUBLISHED
Assigner	redhat
Source Priority	CVE Program / NVD first with legacy fallback
Published	2026-10-01 18:17:15 UTC
Updated	2026-10-16 13:19:24 UTC
Description	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.
