CVE-2025-62987 is a stored Cross-site Scripting (XSS) vulnerability identified in the Builderall Builder for WordPress plugin, specifically affecting versions up to 3.0.1. The vulnerability stems from improper neutralization of input during the generation of web pages, allowing malicious input to be stored and later executed in the context of users visiting the affected site. This type of vulnerability enables attackers to inject arbitrary JavaScript code that executes when other users access the compromised content, potentially leading to session hijacking, unauthorized actions, or data theft. The CVSS v3.1 score of 6.5 reflects a medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges but user interaction, and a scope change indicating that the vulnerability affects components beyond the initially vulnerable module. The impact includes partial loss of confidentiality, integrity, and availability. No known public exploits have been reported yet, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is widely used in WordPress environments, which are prevalent across many European organizations, especially in sectors relying on web presence and digital marketing. The lack of an official patch link suggests that remediation may require vendor updates or temporary mitigations such as disabling the vulnerable plugin or restricting user input capabilities.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of WordPress and associated plugins like Builderall Builder for website creation and management. Exploitation could lead to unauthorized script execution within the context of authenticated users, resulting in session hijacking, credential theft, or unauthorized actions on behalf of users. This can compromise sensitive customer data, disrupt business operations, and damage organizational reputation. Given the medium severity and the requirement for user interaction, the risk is moderate but non-negligible, especially for organizations with high web traffic or those handling sensitive information. Attackers could leverage this vulnerability to conduct targeted phishing campaigns or lateral movement within compromised networks. The vulnerability also poses compliance risks under GDPR if personal data is exposed or mishandled due to exploitation. Organizations in sectors such as e-commerce, finance, and public services, which rely heavily on web platforms, may face increased exposure and potential regulatory scrutiny.

1. Monitor Builderall’s official channels for security patches addressing CVE-2025-62987 and apply updates immediately upon release. 2. Until a patch is available, consider disabling the Builderall Builder plugin or restricting its use to trusted administrators only. 3. Implement strict input validation and output encoding on all user-generated content fields to prevent malicious script injection. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block XSS payloads targeting WordPress plugins. 5. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including stored XSS. 6. Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content within the site. 7. Use Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser. 8. Monitor logs and user activity for unusual behavior indicative of exploitation attempts. 9. Limit plugin installation and updates to verified sources and maintain an inventory of active plugins to reduce attack surface.
