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 a forged HTTP request, causing the victim's browser to perform unwanted actions on a web application in which they are authenticated. In this case, the vulnerability allows attackers to induce users to perform state-changing operations without their consent, potentially modifying plugin settings or other site configurations that rely on this plugin. The CVSS score of 4.3 (medium) reflects that the attack vector is remote (network), requires no privileges, but does require user interaction, and impacts integrity but not confidentiality or availability. The vulnerability does not require the attacker to have authentication credentials, increasing the risk surface. No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The plugin is commonly used in WordPress environments to manage dofollow links on a case-by-case basis, which means that websites relying on this plugin for SEO or link management could be targeted. The lack of CSRF protections such as anti-CSRF tokens or proper validation of request origins is the root cause. This vulnerability could be leveraged to alter link configurations or other plugin-managed settings, potentially impacting site behavior or SEO integrity.

For European organizations, especially those operating WordPress websites with the 'DoFollow Case by Case' plugin installed, this vulnerability poses a risk to the integrity of their web content and configurations. Attackers could exploit this flaw to manipulate link attributes or other plugin settings, potentially degrading SEO performance or redirecting users to malicious sites if combined with other vulnerabilities. While confidentiality and availability are not directly impacted, the integrity compromise could lead to reputational damage, loss of user trust, and indirect financial consequences due to SEO penalties or phishing attacks. Organizations in sectors with high web presence such as e-commerce, media, and digital marketing are particularly at risk. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure. The lack of patches means organizations must rely on interim mitigations until updates are available.

1. Immediately review and restrict administrative and editor-level access to the WordPress sites using this plugin to trusted personnel only. 2. Implement web application firewall (WAF) rules to detect and block suspicious cross-site requests targeting the plugin’s endpoints. 3. Educate users and administrators about phishing and social engineering risks to reduce the likelihood of user interaction leading to exploitation. 4. Monitor plugin vendor communications closely for security patches or updates addressing this vulnerability and apply them promptly once released. 5. If feasible, temporarily disable or remove the 'DoFollow Case by Case' plugin until a patch is available, especially on high-value or public-facing sites. 6. Conduct security audits to ensure that anti-CSRF tokens and proper request validation are implemented in custom or third-party plugins. 7. Employ Content Security Policy (CSP) headers to limit the impact of malicious scripts that could facilitate CSRF attacks. 8. Regularly back up website data and configurations to enable quick restoration if unauthorized changes occur.
