CVE-2025-62734 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Media Library Downloader plugin developed by Michael Revellin-Clerc, affecting all versions up to 1.4.0. CSRF vulnerabilities occur when a web application does not properly verify that requests made to it are intentional and originate from authenticated users. In this case, an attacker can craft malicious web requests that, when executed by an authenticated user, cause the application to perform unintended actions such as downloading or manipulating media library content without the user's consent. The vulnerability arises from the lack of proper anti-CSRF tokens or mechanisms to validate the origin of requests. Although no exploits have been reported in the wild, the vulnerability is publicly disclosed and could be leveraged in targeted attacks. The plugin is typically used in content management systems or media-heavy websites to facilitate media downloads, making it a potential target for attackers aiming to disrupt media management or exfiltrate content. The absence of a CVSS score means severity must be inferred from the nature of the vulnerability: CSRF attacks generally require the victim to be authenticated and to interact with a malicious link or site, but they can lead to unauthorized actions impacting confidentiality and integrity. The vulnerability does not directly affect availability but can be a stepping stone for further exploitation if combined with other vulnerabilities.

For European organizations, especially those relying on the Media Library Downloader plugin for managing media assets, this CSRF vulnerability could lead to unauthorized actions performed under the context of legitimate users. Potential impacts include unauthorized downloading, modification, or deletion of media files, which could disrupt business operations or lead to data leakage. Organizations in sectors such as media, publishing, education, and marketing that heavily use content management systems integrating this plugin are at higher risk. The vulnerability could be exploited to compromise user trust, damage brand reputation, or facilitate further attacks by leveraging unauthorized access. While the direct impact on availability is limited, the integrity and confidentiality of media content are at risk. Given the lack of known exploits, the immediate threat level is moderate, but the risk increases if attackers combine this vulnerability with social engineering to lure authenticated users into triggering malicious requests.

To mitigate CVE-2025-62734, organizations should first verify if they are using the Media Library Downloader plugin version 1.4.0 or earlier and update to a patched version once available. In the absence of an official patch, implement the following controls: 1) Introduce anti-CSRF tokens in all state-changing requests to ensure requests originate from legitimate users. 2) Enforce strict referer header validation to detect and block unauthorized cross-origin requests. 3) Limit the permissions of users interacting with the plugin to minimize potential damage from CSRF attacks. 4) Educate users about the risks of clicking on suspicious links while authenticated. 5) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns. 6) Regularly audit and monitor logs for unusual activity related to media library operations. These measures provide layered defense until an official patch is released.
