CVE-2025-14506 is a stored Cross-Site Scripting (XSS) vulnerability identified in the ConvertForce Popup Builder plugin for WordPress, specifically affecting all versions up to and including 0.0.7. The vulnerability stems from improper neutralization of input during web page generation, classified under CWE-79. The issue lies in the insufficient sanitization and output escaping of the Gutenberg block's entrance_animation attribute, which is used to control popup animations. Authenticated attackers with Author-level privileges or higher can exploit this flaw by injecting arbitrary JavaScript code into pages via this attribute. Once injected, the malicious scripts execute in the context of any user who accesses the compromised page, potentially allowing attackers to hijack user sessions, steal cookies, perform actions on behalf of users, or deface content. The vulnerability has a CVSS 3.1 base score of 6.4, indicating medium severity, with an attack vector of network (remote), low attack complexity, requiring privileges (Author or above), no user interaction, and a scope change due to affecting other components. No public exploits have been reported yet, but the presence of authenticated access requirements limits the attack surface primarily to internal or compromised users. The vulnerability affects all versions of the plugin up to 0.0.7, and no patches have been linked yet. The plugin is used in WordPress environments, which are widely deployed for content management and e-commerce, making this a relevant threat for many organizations.

For European organizations, this vulnerability poses a moderate risk primarily to websites and web applications running WordPress with the ConvertForce Popup Builder plugin installed. The ability for an authenticated Author-level user to inject persistent malicious scripts can lead to session hijacking, unauthorized actions, data theft, and reputational damage. This is particularly impactful for organizations with multiple content authors or contributors, such as media companies, e-commerce platforms, and educational institutions. The compromise of user sessions or administrative accounts could lead to further lateral movement or data breaches. Additionally, the injected scripts could be used to deliver malware or phishing attacks to site visitors, affecting customer trust and compliance with data protection regulations like GDPR. Although exploitation requires authenticated access, insider threats or compromised accounts increase the risk. The lack of available patches at the time of disclosure means organizations must rely on mitigations to reduce exposure. Overall, the impact is significant enough to warrant prompt attention but is mitigated by the privilege requirement and absence of known exploits.

1. Immediately restrict Author-level and higher privileges to trusted users only, minimizing the risk of malicious script injection. 2. Monitor and audit user activities, especially those with elevated privileges, to detect suspicious behavior or unauthorized content changes. 3. Implement web application firewalls (WAFs) with custom rules to detect and block attempts to inject or serve malicious scripts via the entrance_animation attribute or similar vectors. 4. Employ input validation and output encoding at the application level where possible, ensuring that any user-supplied data is properly sanitized before rendering. 5. Regularly review and update WordPress plugins and themes to the latest versions once patches become available. 6. Consider temporarily disabling or replacing the ConvertForce Popup Builder plugin if patching is not immediately possible. 7. Educate content authors about security best practices and the risks of injecting untrusted content. 8. Use Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected websites. 9. Conduct regular vulnerability scans and penetration testing focusing on XSS and privilege escalation vectors. 10. Maintain strong authentication mechanisms, including multi-factor authentication, to reduce the risk of account compromise.
