    Package        : php-twig
    Version        : 2.14.3-1+deb11u4
    CVE ID         : CVE-2024-51754

    Twig is a template language for PHP. In a sandbox, an attacker can call
    `__toString()` on an object even if the `__toString()` method is not allowed by
    the security policy when the object is part of an array or an argument list
    (arguments to a function or a filter for instance).

    For Debian 11 bullseye, this problem has been fixed in version
    2.14.3-1+deb11u4.

    We recommend that you upgrade your php-twig packages.

    For the detailed security status of php-twig please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/php-twig
