CVE-2026-47732 (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 Incorrect Authorization via incomplete CheckToStringNode enforcement in SandboxNodeVisitor. An attacker can invoke __toString() on arbitrary objects reachable from the render context by using Twig language constructs that trigger implicit PHP string coercion without calling SecurityPolicy::checkMethodAllowed(), bypassing sandbox method restrictions.
