CVE-2024-45290: PhpSpreadsheet allows absolute path traversal and Server-Side Request Forgery when opening XLSX file
It’s possible for an attacker to construct an XLSX file which links media from external URLs. When opening the XLSX file, PhpSpreadsheet retrieves the image size and type by reading the file contents, if the provided path is a URL. By using specially crafted php://filter URLs an attacker can leak the contents of any file or URL.
