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.

  1. Oct 7, 2026 · CVE.org

    Updated

    A flaw was found in Foreman. An authenticated attacker with low-level permissions can achieve remote code execution (RCE) by bypassing the safemode sandbox within the templating engine. Due to improper handling of delegated methods, an attacker can append unauthorized functions to the allowed execution list, enabling them to run arbitrary commands on the hosting server.
