The vulnerability identified as CVE-2025-62103 is a Cross-Site Request Forgery (CSRF) issue in the wpmediadownload Media Library File Download plugin for WordPress, affecting versions up to and including 1.4. CSRF vulnerabilities allow attackers to induce authenticated users to perform actions they did not intend by exploiting the trust a web application has in the user's browser. In this case, the vulnerability permits unauthorized commands related to media file downloads within the WordPress media library environment. The attacker can craft a malicious web page or link that, when visited by an authenticated user, triggers the plugin to execute download-related operations without the user's explicit consent. This could lead to unauthorized data access or manipulation of media files. The vulnerability does not require the attacker to have direct authentication credentials but relies on the victim being logged into the affected WordPress site. No CVSS score has been assigned yet, and no patches or known exploits are currently available, indicating the vulnerability is newly disclosed. The lack of CSRF protections such as anti-CSRF tokens or proper referer validation in the plugin's download functionality is the root cause. This vulnerability is particularly concerning for websites that allow multiple users with varying privilege levels to interact with media files, as it could lead to privilege escalation or data leakage.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of media assets managed via WordPress sites using the affected plugin. Attackers could exploit the CSRF flaw to initiate unauthorized downloads or manipulate media files, potentially leading to data leakage or unauthorized distribution of sensitive content. This could damage organizational reputation, violate data protection regulations such as GDPR, and disrupt business operations reliant on media content. The impact is heightened for organizations with collaborative environments where multiple users have authenticated access to media libraries. Additionally, if media files contain sensitive or proprietary information, unauthorized access could lead to intellectual property theft or compliance violations. Although availability impact is limited, the unauthorized actions could indirectly affect service reliability if media content is altered or removed. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after disclosure. European entities with public-facing WordPress sites or intranets using this plugin are particularly vulnerable.

Organizations should immediately inventory their WordPress installations to identify the presence of the wpmediadownload Media Library File Download plugin and its version. Until an official patch is released, administrators should consider disabling or removing the plugin to eliminate the attack surface. Implementing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting the plugin's endpoints can provide interim protection. Site administrators should enforce strict user access controls, limiting plugin usage to trusted users with minimal privileges. Enabling multi-factor authentication (MFA) for WordPress accounts reduces the risk of session hijacking that could facilitate CSRF exploitation. Monitoring web server logs for unusual media download requests or suspicious referrers can help detect attempted exploitation. Once patches become available, prompt application is critical. Additionally, developers maintaining the plugin should incorporate anti-CSRF tokens and validate HTTP referer headers to prevent unauthorized requests. Educating users about the risks of clicking unknown links while authenticated on sensitive sites can reduce social engineering vectors.
