CVE-2026-5742
CWE-79Published: April 9, 2026· Updated: Apr 13, 2026
Official Description
The UsersWP plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.2.60. This is due to insufficient input sanitization of user-supplied URL fields and improper output escaping when rendering user profile data in badge widgets. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that will execute whenever a user accesses a page containing the affected badge widget.
Technical Analysis
CVE-2026-5742 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
