CVE-2025-24986Network attack vector

Unauthenticated code execution via unsandboxed Jinja templates

Published Mar 11, 2025 · Updated Feb 13, 2026

Template injection in Microsoft Prompt flow allows remote attackers to execute code over a network through crafted Jinja templates. The render_jinja_template_content and render_jinja_template helpers instantiate unrestricted Jinja Template objects for attacker-controlled template content. No privileges or user interaction are required when an exposed flow accepts such a template, allowing commands to run with the service process's permissions.
