CVE-2025-53292 is a medium severity vulnerability classified under CWE-79, indicating an improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). Specifically, this vulnerability affects the samsk WP DataTable plugin for WordPress, versions up to and including 0.2.7. The vulnerability is DOM-based XSS, meaning that malicious scripts are executed as a result of unsafe client-side manipulation of the Document Object Model (DOM) rather than server-side injection. An attacker with at least low privileges (PR:L) and requiring user interaction (UI:R) can exploit this vulnerability remotely (AV:N) with low attack complexity (AC:L). The vulnerability impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L) and has a scope change (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises because the plugin does not properly sanitize or neutralize user-supplied input before incorporating it into the web page's DOM, allowing attackers to inject malicious JavaScript code. This can lead to session hijacking, defacement, or redirection to malicious sites, potentially compromising user data or the website's integrity.

For European organizations using WordPress sites with the samsk WP DataTable plugin, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information, or manipulation of website content, undermining trust and potentially violating data protection regulations such as GDPR. Since the vulnerability requires some level of user interaction and privileges, targeted phishing or social engineering campaigns could be used to exploit it. The scope change indicates that the attack could affect other components or users beyond the initially vulnerable plugin, increasing the risk of broader compromise. Organizations in sectors with high web presence, such as e-commerce, media, and public services, may face reputational damage and operational disruptions. Additionally, the medium CVSS score reflects a moderate but non-negligible threat that should be addressed promptly to prevent escalation.

European organizations should immediately audit their WordPress installations to identify the presence of the samsk WP DataTable plugin, particularly versions up to 0.2.7. Until an official patch is released, consider the following mitigations: 1) Disable or remove the vulnerable plugin if it is not critical to operations. 2) Implement Web Application Firewall (WAF) rules to detect and block suspicious DOM-based XSS payloads targeting the plugin's known input vectors. 3) Enforce Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. 4) Educate users and administrators about the risks of clicking on untrusted links or interacting with suspicious content that could trigger the XSS. 5) Monitor web server and application logs for unusual activity indicative of exploitation attempts. 6) Plan for rapid deployment of patches once they become available from the vendor. 7) Conduct code reviews or penetration testing focused on client-side input handling within the plugin to identify any additional weaknesses.
