What is CVE-2023-54341?

Webgrind versions 1.1 and earlier are vulnerable to a reflected cross-site scripting (XSS) flaw, which enables unauthenticated attackers to inject malicious scripts via the 'file' parameter in index.php. This vulnerability arises from insufficient input encoding of user-controlled data, allowing attackers to execute arbitrary JavaScript in the browsers of unsuspecting users by crafting specific URLs. Proper validation and encoding practices are essential to mitigate such risks.
