CVE-2025-62102 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the DoFollow Case by Case plugin developed by apasionados, affecting versions up to and including 3.5.1. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting unauthorized requests to a web application, leveraging the user's active session to perform actions without their consent. This plugin, likely used in content management systems to manage 'dofollow' link behavior on a case-by-case basis, fails to implement sufficient anti-CSRF protections such as tokens or origin validation. Consequently, an attacker can craft malicious web pages or links that, when visited by an authenticated user, cause unintended state-changing operations on the target site. Although no exploits are currently known in the wild, the vulnerability is publicly disclosed and assigned a CVE identifier, indicating recognition and potential risk. The lack of a CVSS score suggests the need for a manual severity assessment. The vulnerability primarily threatens the integrity of the affected web applications by enabling unauthorized actions, and may also impact availability if exploited to perform disruptive operations. The attack requires the victim to be authenticated but does not require additional user interaction beyond visiting a malicious page. The plugin's market penetration and usage patterns will influence the scope of affected systems. No patches or fixes are currently linked, indicating that users must rely on mitigations until an official update is released.

For European organizations, the impact of CVE-2025-62102 depends on the extent to which the DoFollow Case by Case plugin is deployed within their web infrastructure. Organizations using this plugin in content management systems, particularly those managing SEO or link behaviors, could face unauthorized changes to website content or configurations. This could lead to integrity breaches, such as unauthorized link modifications, which may affect SEO rankings or website trustworthiness. In more severe scenarios, attackers could exploit the vulnerability to perform administrative actions, potentially disrupting website availability or exposing sensitive information indirectly. The vulnerability requires an authenticated user session, so the risk is higher in environments with many authenticated users or where users have elevated privileges. European organizations in sectors such as e-commerce, media, and digital marketing, which rely heavily on CMS platforms, may be particularly vulnerable. Additionally, reputational damage and compliance risks under regulations like GDPR could arise if the vulnerability leads to unauthorized data manipulation or exposure.

To mitigate CVE-2025-62102, organizations should first verify whether the DoFollow Case by Case plugin is in use within their web environments. If so, immediate steps include restricting plugin usage to trusted administrators and limiting user privileges to reduce the risk of exploitation. Implementing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide interim protection. Developers and administrators should ensure that all state-changing requests require anti-CSRF tokens and validate the HTTP Referer or Origin headers to confirm legitimate request sources. Monitoring web server logs for unusual or unauthorized requests can help detect exploitation attempts. Until an official patch is released, consider disabling or removing the plugin if feasible. Additionally, educating users about the risks of visiting untrusted websites while authenticated can reduce the likelihood of CSRF attacks. Once a patch or update is available from the vendor, promptly apply it and verify the effectiveness of the fix through security testing.
