Summary
Sharp is Vulnerable to Path Traversal via Unsanitized Extension in FileUtil
Details

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.
