Sharp is Vulnerable to Path Traversal via Unsanitized Extension in FileUtil_CVE-2026-33686

{
    "lastseen": "",
    "description": "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'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.",
