CVE-2025-7399 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Betheme WordPress theme developed by MuffinGroup. This vulnerability affects all versions up to and including 28.1.3. The root cause is insufficient input sanitization and output escaping in an Elementor display setting, which allows authenticated users with Contributor-level access or higher to inject arbitrary JavaScript code into pages. When other users visit these compromised pages, the malicious scripts execute in their browsers. This vulnerability leverages CWE-79, which pertains to improper neutralization of input during web page generation. The attack vector is remote network access (AV:N), with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality and integrity loss but no availability impact, resulting in a CVSS v3.1 base score of 6.4 (medium severity). Stored XSS can lead to session hijacking, defacement, phishing, or malware distribution. Since the vulnerability requires authenticated access at Contributor level or above, exploitation is limited to users with some level of trust in the system, but WordPress sites often have multiple contributors, increasing risk. No known exploits in the wild have been reported yet, and no official patches or updates have been linked at the time of publication. This vulnerability is particularly relevant for websites using the Betheme theme combined with Elementor page builder, which is a popular setup in WordPress environments.

For European organizations, the impact of CVE-2025-7399 can be significant, especially for those relying on WordPress sites for corporate communication, e-commerce, or customer engagement. Stored XSS can compromise user accounts, steal sensitive information, and damage brand reputation. Since the vulnerability requires Contributor-level access, insider threats or compromised contributor accounts pose a risk. Attackers could leverage this to escalate privileges or conduct targeted phishing campaigns against employees or customers. The integrity of website content can be undermined, leading to misinformation or loss of trust. Additionally, regulatory frameworks like GDPR impose strict requirements on protecting personal data, and a successful XSS attack could lead to data breaches triggering compliance violations and fines. The medium CVSS score indicates a moderate risk, but the widespread use of WordPress and Betheme in Europe increases the attack surface. Organizations with public-facing websites or intranets using this theme should consider the threat seriously to avoid reputational and operational damage.

1. Immediate mitigation should include restricting Contributor-level access to trusted users only and auditing existing user permissions to minimize risk exposure. 2. Implement Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads targeting Elementor and Betheme-specific parameters. 3. Regularly monitor website content for unauthorized script injections or unexpected changes, using automated scanning tools tailored for WordPress environments. 4. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of XSS attacks. 5. Since no official patch is available yet, consider temporarily disabling or limiting the use of Elementor display settings that allow user input until a fix is released. 6. Educate contributors about phishing and social engineering risks to prevent account compromise. 7. Once a patch is released, prioritize immediate update of the Betheme theme and Elementor plugins. 8. Conduct penetration testing focused on XSS vulnerabilities in WordPress sites to identify and remediate similar issues proactively.
