Hi,

The following vulnerability was published for smarty4.

CVE-2022-29221[0]:
| Smarty is a template engine for PHP, facilitating the separation of
| presentation (HTML/CSS) from application logic. Prior to versions
| 3.1.45 and 4.1.1, template authors could inject php code by choosing a
| malicious {block} name or {include} file name. Sites that cannot fully
| trust template authors should upgrade to versions 3.1.45 or 4.1.1 to
| receive a patch for this issue. There are currently no known
| workarounds.
