CVE-2025-13217: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ultimatemember Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the YouTube Video 'value' field in all versions up to, and including, 2.11.0. This is due to insufficient input sanitization and output escaping on user-supplied YouTube video URLs in the `um_profile_field_filter_hook__youtube_video()` function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the injected user's profile page.
AI Analysis
Technical Summary
CVE-2025-13217 is a stored cross-site scripting vulnerability in the Ultimate Member WordPress plugin (up to version 2.11.0). It occurs due to improper neutralization of input in the YouTube video 'value' field, specifically within the um_profile_field_filter_hook__youtube_video() function. Authenticated users with at least Subscriber privileges can inject arbitrary scripts via crafted YouTube video URLs, which are then executed in the context of any user viewing the compromised profile page. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability.
Potential Impact
The vulnerability allows authenticated attackers with Subscriber-level access or higher to inject and execute arbitrary JavaScript in the context of other users viewing the injected profile pages. This can lead to theft of session tokens, user impersonation, or other malicious actions limited to the scope of the affected site. The CVSS score of 6.4 reflects a medium severity with low complexity and no user interaction required beyond authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Subscriber-level user capabilities if possible and monitor for suspicious profile content. Avoid allowing untrusted users to input YouTube video URLs or disable the affected profile field as a temporary workaround.
