CVE-2025-54589

copyparty Reflected XSS via Filter Parameter

Published Jul 31, 2025 CVSS 3.1 · 6.3 Medium EPSS 2.4% KEV · Not listed
Description
Copyparty is a portable file server. In versions 1.18.6 and below, when accessing the recent uploads page at `/?ru`, users can filter the results using an input field at the top. This field appends a filter parameter to the URL, which reflects its value directly into a `<script>` block without proper escaping, allowing for reflected Cross-Site Scripting (XSS) and can be exploited against both authenticated and unauthenticated users. This is fixed in version 1.18.7.
