The Ultimate Endpoints With Rest Api plugin for WordPress suffers from a reflected XSS vulnerability due to improper neutralization of input in the 'page' parameter. This allows unauthenticated attackers to inject malicious scripts that execute in the context of a victim's browser when they click on a crafted link. The vulnerability affects all versions up to and including 2.2.2. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of sensitive information, session hijacking, or other malicious actions limited to the user's session. There is no indication of direct impact on system availability or integrity beyond the browser context. No known exploits in the wild have been reported.

Patch status is not yet confirmed — no official fix or patch information is currently available. Users should monitor the vendor's advisory channels for updates. Until a fix is released, consider applying web application firewall (WAF) rules to detect and block suspicious input in the 'page' parameter or disable the plugin if feasible to reduce exposure.
