    Multiple security vulnerabilities were discovered in Twig, a template     engine for PHP, which could result in PHP code injection, sandbox bypass     or cross-site scripting.

    For the stable distribution (trixie), these problems have been fixed in     version 3.27.0-0+deb13u1.

    We recommend that you upgrade your php-twig packages.
