Foreman: safemode bypass leading to rce
Published Oct 1, 2026 · corrected/updated Oct 7, 2026 · Red Hat Red Hat Satellite 6.16 for RHEL 8 · evidence confidence medium
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.
