The UsersWP plugin for WordPress, versions up to and including 1.2.60, contains a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, user-supplied URL fields are not sufficiently sanitized, and user profile data rendered in badge widgets lacks proper output escaping. This allows authenticated attackers with subscriber-level privileges or higher to inject arbitrary web scripts that execute when any user accesses a page containing the affected badge widget. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or official remediation level has been published by the vendor. The plugin is not a cloud service, so remediation depends on plugin updates.

Successful exploitation allows an authenticated user with subscriber-level or higher privileges to inject persistent malicious scripts into user profile badge widgets. These scripts execute in the context of other users viewing the affected pages, potentially leading to theft of session tokens, user impersonation, or other confidentiality and integrity impacts. Availability is not affected. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting subscriber-level user input in URL fields or disabling the affected badge widgets to reduce exposure. Monitor vendor channels for updates and apply patches promptly once available.
