What is CVE-2026-12544?

A vulnerability in Foreman was identified involving flawed initialization logic within the foreman-rake process.

This weakness permits Server-Side Template Injection (SSTI) and insecure deserialization, potentially resulting in unauthorized remote code execution, complete infrastructure compromise, and increased supply chain vulnerabilities.
