What is CVE-2026-107625?

The Ultimate Member Plugin for WordPress is susceptible to a stored cross-site scripting vulnerability through the 'user_url' parameter. This flaw arises from inadequate input sanitization and output escaping, allowing authenticated attackers with subscriber-level access and above to embed arbitrary web scripts in pages. This exploitation can lead to the execution of malicious scripts when users access the compromised page, typically triggered by clicking a link on the attacker's profile. This issue affects all versions of the plugin up to and including 2.14.0, necessitating prompt action for mitigation.

Affected Version(s)

Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin 0 <= 2.14.0
