Deeper analysis

CVE-2025-23639 is a Cross-Site Request Forgery (CSRF) vulnerability in the WordPress plugin MDC YouTube Downloader (mdc-youtube-downloader) developed by Nazmul Ahsan that enables Stored Cross-Site Scripting (XSS). The flaw, tied to CWE-352, affects all versions of the plugin up to and including 3.0.0.

With a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), the vulnerability is exploitable over the network by unauthenticated attackers with low complexity, though it requires user interaction. An attacker can trick an authenticated user into submitting a malicious request via a crafted webpage, leading to the storage of XSS payloads that execute in the context of other users viewing affected content.

The Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/mdc-youtube-downloader/vulnerability/wordpress-mdc-youtube-downloader-plugin-3-0-0-csrf-to-stored-xss-vulnerability?_s_id=cve) documents the CSRF-to-stored-XSS issue specifically in version 3.0.0 of the WordPress MDC YouTube Downloader plugin.
