Hi, The following vulnerability was published for php-twig. CVE-2022-39261[0]: | Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x | prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue when the | filesystem loader loads templates for which the name is a user input. | It is possible to use the `source` or `include` statement to read | arbitrary files from outside the templates' directory when using a | namespace like `@somewhere/../some.file`. In such a case, validation | is bypassed. Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for | validation of such template names. There are no known workarounds | aside from upgrading. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
