CVE-2025-14130 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the Post Like Dislike plugin for WordPress, developed by cuvixsystem. This vulnerability exists in all versions up to and including 1.0 and is caused by improper neutralization of input during web page generation, specifically involving the $_SERVER['PHP_SELF'] variable. The plugin fails to adequately sanitize and escape this variable, which can be manipulated by an attacker to inject arbitrary JavaScript code into web pages. Because the vulnerability is reflected, the malicious script is embedded in a crafted URL or request that, when clicked or visited by a user, causes the script to execute in the context of the victim's browser. This can lead to theft of session cookies, defacement, or other malicious actions impacting the confidentiality and integrity of user data. The vulnerability does not require authentication, making it accessible to unauthenticated attackers, but does require user interaction (clicking a malicious link). The CVSS v3.1 score is 6.1, indicating a medium severity level, with attack vector network, low attack complexity, no privileges required, user interaction required, and scope changed. No patches or exploit code are currently publicly available, and no known exploits in the wild have been reported. The vulnerability is classified under CWE-79, which covers improper neutralization of input leading to XSS attacks. Given WordPress's widespread use in Europe, especially for public-facing websites, this vulnerability poses a tangible risk to organizations using the affected plugin. Attackers could leverage this flaw to perform targeted phishing campaigns or session hijacking, potentially compromising user accounts or sensitive information.

For European organizations, the impact of CVE-2025-14130 can be significant, especially for those relying on WordPress sites with the Post Like Dislike plugin installed. Successful exploitation can lead to unauthorized script execution in users' browsers, enabling session hijacking, credential theft, or redirection to malicious sites. This undermines user trust and can result in data breaches or reputational damage. Although the vulnerability does not affect system availability, the compromise of confidentiality and integrity can have regulatory implications under GDPR, particularly if personal data is exposed. Organizations operating e-commerce, government, or media websites are at higher risk due to their public visibility and user base. The need for user interaction (clicking a malicious link) somewhat limits the attack scope but does not eliminate risk, as phishing remains a common and effective attack vector. Additionally, the reflected nature of the XSS means that attackers can craft URLs for social engineering campaigns targeting specific users or groups within European organizations.

1. Monitor for and apply security updates or patches from the plugin vendor immediately once available. 2. If patches are not yet released, consider temporarily disabling or removing the Post Like Dislike plugin to eliminate exposure. 3. Deploy Web Application Firewalls (WAFs) configured to detect and block reflected XSS attempts, especially those targeting the $_SERVER['PHP_SELF'] parameter. 4. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected sites. 5. Educate users and staff about the risks of clicking suspicious links and encourage verification of URLs before interaction. 6. Conduct regular security audits and penetration testing on WordPress installations to identify and remediate similar vulnerabilities. 7. Use security plugins that provide input sanitization and output escaping enhancements as an additional layer of defense. 8. Monitor web server logs for unusual requests involving the PHP_SELF parameter that may indicate exploitation attempts.
