CVE-2025-8687 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, found in the Enter Addons – Ultimate Template Builder for Elementor WordPress plugin. This vulnerability exists in all versions up to and including 2.2.7 due to improper neutralization of input during web page generation. Specifically, the Countdown and Image Comparison widgets fail to adequately sanitize and escape user-supplied attributes, allowing authenticated users with contributor-level access or higher to inject arbitrary JavaScript code into pages. When other users visit these compromised pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions on behalf of the victim. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting medium severity, with an attack vector of network, low attack complexity, requiring privileges but no user interaction, and with a scope change indicating that the vulnerability affects resources beyond the initially vulnerable component. No public exploits are known at this time, but the risk remains significant due to the ease of exploitation by authenticated users and the potential impact on confidentiality and integrity of user data. The plugin is widely used in WordPress environments, which are prevalent in many European organizations for website management and content publishing.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of web applications running WordPress with the affected plugin. Attackers with contributor-level access can embed malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to session hijacking, theft of sensitive information, unauthorized actions, or defacement. This can damage organizational reputation, lead to data breaches, and cause compliance issues under regulations like GDPR. Since WordPress powers a significant portion of websites in Europe, including those of SMEs, public institutions, and enterprises, the impact can be widespread. Organizations with multiple content contributors or editors are particularly vulnerable, as these roles can be leveraged to exploit the flaw. The vulnerability does not affect availability directly but can indirectly cause service disruption through reputational damage or administrative lockout if attackers escalate privileges. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability is public.

1. Immediately restrict contributor-level privileges to trusted users only, minimizing the risk of malicious script injection. 2. Implement strict input validation and output escaping on all user-supplied data within the affected widgets, either by applying custom filters or using security plugins that enforce sanitization. 3. Monitor and audit content changes made by contributors to detect suspicious script injections early. 4. Disable or remove the Countdown and Image Comparison widgets if they are not essential to reduce the attack surface. 5. Regularly update the Enter Addons plugin as soon as the vendor releases a security patch addressing this vulnerability. 6. Employ Web Application Firewalls (WAF) with rules to detect and block common XSS payloads targeting WordPress plugins. 7. Educate content contributors about the risks of injecting untrusted code or content. 8. Conduct periodic security assessments and penetration tests focusing on user input handling in WordPress environments.
