Hi,

The following vulnerability was published for snappy, which is bundled
by civicrm:

CVE-2023-28115[0]:
| Snappy is a PHP library allowing thumbnail, snapshot or PDF generation
| from a url or a html page. Prior to version 1.4.2, Snappy is
| vulnerable to PHAR deserialization due to a lack of checking on the
| protocol before passing it into the `file_exists()` function. If an
| attacker can upload files of any type to the server he can pass in the
| phar:// protocol to unserialize the uploaded file and instantiate
| arbitrary PHP objects. This can lead to remote code execution
| especially when snappy is used with frameworks with documented POP
| chains like Laravel/Symfony vulnerable developer code. If a user can
| control the output file from the `generateFromHtml()` function, it
| will invoke deserialization. This vulnerability is capable of remote
| code execution if Snappy is used with frameworks or developer code
| with vulnerable POP chains. It has been fixed in version 1.4.2.
