CVE-2025-7732 is a stored Cross-Site Scripting (XSS) vulnerability affecting the 'Lazy Load for Videos' WordPress plugin developed by kevinweber, present in all versions up to and including 2.18.7. The vulnerability arises from improper input sanitization and output escaping in the plugin's lazy-loading handlers. Specifically, the plugin’s JavaScript registration handlers process client-supplied 'data-video-title' and 'href' attributes by decoding HTML entities and directly injecting them into DOM sinks without adequate escaping or validation. This flaw allows an authenticated attacker with Contributor-level or higher privileges to inject arbitrary malicious scripts into pages. These scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking, privilege escalation, or other malicious actions. The vulnerability does not require user interaction beyond visiting the affected page and has a CVSS 3.1 base score of 6.4, indicating a medium severity level. The attack vector is network-based, with low attack complexity, requiring privileges but no user interaction, and impacts confidentiality and integrity with a scope change due to the potential for script execution affecting other users. No known exploits in the wild have been reported as of the publication date (August 27, 2025). The absence of patches at the time of reporting increases the urgency for mitigation.

For European organizations, this vulnerability poses a significant risk especially for those relying on WordPress websites that utilize the Lazy Load for Videos plugin. Exploitation could lead to unauthorized script execution within the context of the affected websites, enabling attackers to steal sensitive user data such as authentication cookies, perform actions on behalf of users, or deliver further malware payloads. This can damage organizational reputation, lead to data breaches, and violate data protection regulations such as the GDPR, potentially resulting in legal and financial penalties. Given the medium severity and the requirement for authenticated access, internal threat actors or compromised contributor accounts could be leveraged to exploit this vulnerability. The scope of impact extends to any user visiting the infected pages, including customers and employees, increasing the risk of widespread compromise. Additionally, the cross-site scripting nature of the vulnerability can facilitate phishing attacks or drive-by downloads, further amplifying the threat landscape for European entities.

European organizations should immediately audit their WordPress installations to identify the presence of the Lazy Load for Videos plugin and verify the version in use. Until an official patch is released, organizations should consider disabling or uninstalling the plugin to eliminate the attack surface. If removal is not feasible, implement strict role-based access controls to limit Contributor-level and higher privileges to trusted users only, minimizing the risk of malicious script injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting 'data-video-title' and 'href' attributes. Additionally, enable Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. Regularly monitor website content for unauthorized changes and conduct security scans to detect potential XSS payloads. Finally, maintain vigilance for updates from the plugin vendor and apply patches promptly once available.
