      <title>CVE-2026-33686 — Sharp is Vulnerable to Path Traversal via Unsanitized Extension in FileUtil</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-33686</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; code16 sharp&lt;/p&gt;
&lt;p&gt;Sharp is a content management framework built for Laravel as a package. Versions prior to 9.20.0 have a path traversal vulnerability  in the FileUtil class. The application fails to sanitize file extensions properly, allowing path separators to be passed into the storage layer. In `src/Utils/FileUtil.php`, the `FileUtil::explodeExtension()` function extracts a file&amp;#39;s extension by splitting the filename at the last dot. This issue has been patched in version 9.20.0 by properly sanitizing the extension using `pathinfo(PATHINFO_EXTENSION)` instead of `strrpos()`, alongside applying strict regex replacements to both the base name and the extension.&lt;/p&gt;</description>
