Package : php-twig
CVE ID : CVE-2022-23614

Marlon Starkloff discovered that twig, a template engine for PHP, did
not correctly enforce sandboxing. This would allow a malicious user to
execute arbitrary code.

For the stable distribution (bullseye), this problem has been fixed in
version 2.14.3-1+deb11u1.

We recommend that you upgrade your php-twig packages.
