CVE-2025-64047 identifies a Cross Site Scripting (XSS) vulnerability in OpenRapid RapidCMS version 1.3.1, specifically within the /user/user-move.php script. XSS vulnerabilities occur when an application does not properly sanitize user-supplied input, allowing attackers to inject malicious client-side scripts that execute in the browsers of other users. In this case, the vulnerability resides in a user management function, which may be accessible to authenticated users or administrators. Exploitation could enable attackers to steal session cookies, perform actions on behalf of victims, or deliver malware. Although no CVSS score or known exploits are currently documented, the vulnerability's presence in a CMS component that handles user operations increases the risk profile. The lack of patch links indicates that a fix has not yet been released, emphasizing the need for immediate mitigation. The vulnerability's exploitation requires the victim to interact with a crafted URL or input, but does not necessarily require elevated privileges to trigger. This vulnerability affects the confidentiality and integrity of user sessions and data, but does not directly impact system availability. The absence of known exploits suggests limited active threat but does not preclude future exploitation. Organizations using OpenRapid RapidCMS should audit their installations, review user input handling in the affected endpoint, and prepare to deploy patches once available.

For European organizations, the impact of this XSS vulnerability can be significant, especially for those relying on OpenRapid RapidCMS for managing web content and user accounts. Successful exploitation could lead to session hijacking, enabling attackers to impersonate legitimate users, including administrators, potentially leading to unauthorized data access or manipulation. This can compromise the confidentiality and integrity of sensitive information, including personal data protected under GDPR. Additionally, attackers could use the vulnerability to deliver malicious payloads to users, increasing the risk of malware infections or phishing attacks. While the vulnerability does not directly affect availability, the reputational damage and potential regulatory penalties from data breaches could be severe. Organizations in sectors such as government, finance, healthcare, and media, which often use CMS platforms and handle sensitive data, are particularly at risk. The lack of an official patch means organizations must rely on interim mitigations, increasing operational overhead and risk exposure until a fix is released.

1. Immediately audit and monitor all instances of OpenRapid RapidCMS 1.3.1 for unusual activity, especially around the /user/user-move.php endpoint. 2. Implement strict input validation and output encoding on all user-supplied data in the affected script to neutralize malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4. Restrict access to the /user/user-move.php endpoint to trusted and authenticated users only, applying the principle of least privilege. 5. Educate users and administrators about the risks of clicking on suspicious links or inputs that could trigger XSS attacks. 6. Regularly back up CMS data and configurations to enable quick recovery if exploitation occurs. 7. Engage with the vendor or community to obtain patches or updates as soon as they become available and apply them promptly. 8. Use web application firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting this vulnerability. 9. Conduct penetration testing focused on XSS vectors in the CMS environment to identify and remediate other potential weaknesses.
