CVE-2025-7439 is a stored Cross-Site Scripting (XSS) vulnerability affecting the yeashir Anber Elementor Addon plugin for WordPress, specifically in all versions up to and including 1.0.1. The vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. The flaw exists in the handling of the parameter $anber_item['button_link']['url'], where insufficient input sanitization and output escaping allow an authenticated attacker with Contributor-level privileges or higher 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 unauthorized actions performed on behalf of the victim user. The vulnerability does not require user interaction to trigger once the malicious content is stored and viewed, and it affects the confidentiality and integrity of user data. The CVSS v3.1 score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, requiring privileges (Contributor or above), no user interaction, and a scope change due to the potential impact on other users. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is particularly concerning for WordPress sites using the Anber Elementor Addon plugin, which is commonly used to enhance page-building capabilities.

For European organizations, this vulnerability poses a moderate risk primarily to websites and web applications built on WordPress that utilize the Anber Elementor Addon plugin. Exploitation could lead to unauthorized script execution affecting site visitors and administrators, potentially resulting in theft of session cookies, defacement, or unauthorized actions performed with elevated privileges. This can damage organizational reputation, lead to data breaches involving personal data protected under GDPR, and disrupt business operations. Given the widespread use of WordPress in Europe for corporate, governmental, and e-commerce websites, the vulnerability could affect a broad range of sectors including finance, healthcare, education, and public administration. The requirement for Contributor-level access limits exploitation to insiders or compromised accounts, but this is a realistic threat vector in many organizations. The lack of a patch increases exposure time, and the stored nature of the XSS means persistent risk until remediated. The scope change in CVSS indicates that the impact extends beyond the initially compromised component to other users, increasing the potential damage.

European organizations should immediately audit their WordPress installations to identify the presence of the yeashir Anber Elementor Addon plugin and its version. Until an official patch is released, organizations should consider the following specific mitigations: 1) Restrict Contributor-level access strictly to trusted users and review user permissions to minimize the number of users who can inject content. 2) Implement Web Application Firewall (WAF) rules tailored to detect and block malicious script payloads targeting the vulnerable parameter. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. 4) Conduct thorough input validation and output encoding on any user-generated content, if custom code or overrides are used. 5) Monitor logs and user activity for suspicious behavior indicative of exploitation attempts. 6) Educate site administrators and content contributors about the risks and signs of XSS attacks. Once a patch is available, prioritize immediate deployment and verify the fix through testing. Additionally, consider isolating or disabling the vulnerable plugin if feasible until remediation is complete.
