What is CVE-2025-13217?
The Ultimate Member plugin for WordPress is susceptible to stored cross-site scripting due to inadequate sanitization and output escaping of user-supplied YouTube video URLs. This vulnerability allows authenticated users with Subscriber-level access and higher to inject malicious scripts into user profile pages. When other users access these manipulated profiles, the injected scripts execute, potentially compromising user data and site integrity. It is essential for site administrators to update their installations to mitigate this risk.
