CVE-2025-62012 is a cross-site scripting (XSS) vulnerability identified in the CodexThemes TheGem (Elementor) WordPress plugin, affecting versions up to and including 5.10.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious scripts into web content. This flaw can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), but requires the attacker to have some privileges (PR:L) and user interaction (UI:R) to succeed. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The scope is changed (S:C), meaning the vulnerability can impact resources beyond the initially vulnerable component. Successful exploitation can lead to partial loss of confidentiality, integrity, and availability, such as session hijacking, unauthorized actions on behalf of users, or defacement of web pages. No public exploits are known at this time, but the plugin’s widespread use in WordPress sites makes it a significant risk. The vulnerability was reserved in early October 2025 and published in November 2025, with no patch links currently available, indicating that remediation may still be pending. TheGem (Elementor) is popular among European web developers, increasing the likelihood of targeted attacks in this region. The vulnerability requires authenticated access and user interaction, which somewhat limits the attack surface but does not eliminate the threat, especially in environments with many users or where phishing is feasible.

For European organizations, this vulnerability poses a risk primarily to websites and web applications using the TheGem (Elementor) plugin on WordPress. Exploitation can lead to unauthorized script execution in the context of legitimate users, potentially resulting in session hijacking, theft of sensitive information, unauthorized actions, and website defacement. This can damage organizational reputation, lead to data breaches, and disrupt services. Given the plugin’s popularity in Europe, especially among SMEs and digital agencies, a successful attack could have widespread consequences. The requirement for user interaction and some privileges reduces the likelihood of mass exploitation but does not prevent targeted attacks, especially spear-phishing campaigns. The vulnerability’s impact on confidentiality, integrity, and availability makes it a concern for organizations handling personal data under GDPR, as breaches could lead to regulatory penalties. Additionally, compromised websites can be used as vectors for further attacks or malware distribution, amplifying the threat to the broader European internet ecosystem.

European organizations should take proactive steps to mitigate this vulnerability: 1) Monitor CodexThemes and Elementor plugin updates closely and apply patches immediately once released. 2) Implement strict input validation and sanitization on all user inputs, especially those rendered in web pages. 3) Deploy Content Security Policies (CSP) to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4) Limit user privileges to the minimum necessary to reduce the risk posed by authenticated attackers. 5) Educate users about phishing and social engineering tactics that could trigger the vulnerability. 6) Conduct regular security audits and penetration testing focused on web application vulnerabilities. 7) Use Web Application Firewalls (WAFs) configured to detect and block XSS payloads targeting TheGem (Elementor). 8) Monitor logs and user activity for signs of suspicious behavior indicative of exploitation attempts. 9) Consider isolating or sandboxing critical web components to limit the scope of potential compromise. 10) Maintain backups and incident response plans to quickly recover from any successful exploitation.
