CVE-2026-46633 (opens in a new tab)How to fix?
Upgrade twig/twig to version 3.26.0 or higher.
Overview
twig/twig is a flexible, fast, and secure template language for PHP.
Affected versions of this package are vulnerable to Arbitrary Code Injection via template name handling in the {% use %} tag compilation path. An attacker can execute arbitrary PHP code by supplying a crafted template name containing a single quote, which breaks out of the generated PHP string literal in the compiled cache file. This allows code injection during template compilation and bypasses Twig sandbox restrictions, since {% use %} is allowed regardless of the configured sandbox policy.
