CVE-2024-6668 is a medium-severity vulnerability affecting the ProfilePro WordPress plugin up to version 1.3. The vulnerability is classified as CWE-79, indicating a Cross-Site Scripting (XSS) flaw. Specifically, the plugin fails to properly sanitize and escape certain input parameters and lacks adequate access controls. This deficiency allows users with minimal privileges, as low as the subscriber role, to inject malicious scripts into web pages viewed by other users. The vulnerability is exploitable remotely (AV:N) with low attack complexity (AC:L) but requires some privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the attack can impact resources beyond the vulnerable component. The impact includes limited confidentiality and integrity loss (C:L/I:L) but no availability impact (A:N). Since the vulnerability allows low-privileged users to execute scripts in the context of other users, it can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of victims. The lack of proper access controls exacerbates the risk by enabling exploitation from non-administrative accounts. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 15, 2025, and was reserved on July 10, 2024. The ProfilePro plugin is not widely known, and the vendor is unspecified, which may complicate mitigation efforts and increase risk if the plugin is in use without active maintenance.

For European organizations using WordPress sites with the ProfilePro plugin, this vulnerability poses a tangible risk of targeted XSS attacks originating from low-privileged users. Such attacks can compromise user sessions, steal sensitive information, or perform unauthorized actions within the web application. This is particularly concerning for organizations handling personal data under GDPR, as exploitation could lead to data breaches and regulatory penalties. The vulnerability's ability to escalate impact beyond the initial component (scope changed) means that attackers could affect other parts of the web application or user accounts. Public-facing websites, intranets, or portals with subscriber-level user registrations are especially vulnerable. The medium severity indicates a moderate risk, but the ease of exploitation by low-privileged users and the potential for data confidentiality and integrity loss make it a significant concern. European organizations relying on WordPress plugins without rigorous vetting or update processes may face increased exposure. Additionally, the absence of patches and vendor information complicates timely remediation, potentially prolonging the window of vulnerability.

1. Immediate mitigation should include auditing all WordPress sites for the presence of the ProfilePro plugin and identifying affected versions (up to 1.3). 2. If the plugin is found, disable or remove it until a patch or update is available. 3. Restrict user roles and permissions to minimize the number of users with subscriber or higher roles, especially on sites where untrusted users can register. 4. Implement Web Application Firewall (WAF) rules to detect and block typical XSS payloads targeting the plugin's parameters. 5. Employ Content Security Policy (CSP) headers to reduce the impact of potential XSS by restricting script execution sources. 6. Monitor logs for unusual activity or attempts to exploit XSS vectors associated with the plugin. 7. Engage with the plugin vendor or community to obtain updates or patches and apply them promptly once available. 8. Educate site administrators about the risks of installing plugins from unknown or unverified sources and enforce strict plugin management policies. 9. Consider deploying runtime application self-protection (RASP) solutions that can detect and block XSS attacks dynamically.
