Description
A flaw was found in Foreman. This vulnerability allows an authenticated remote attacker with low-level read permissions to achieve arbitrary code execution on the underlying server. By manipulating the permitted methods list within the template rendering engine, an attacker can bypass the safemode sandbox isolation and execute unauthorized commands directly on the host system.
