Description

A flaw was found in Foreman. The foreman-rake initialization logic in /usr/share/foreman/config/settings.rb contains a vulnerable code pattern where configuration data is processed through two distinct executable layers. This creates a multi-stage execution chain that allows for both Server-Side Template Injection (SSTI) and insecure deserialization. This vulnerability can lead to remote code execution, total infrastructure compromise and supply chain risk.
