Executive Summary

This is a Contributor Cross Site Scripting (XSS) vulnerability found in the WordPress OAuth Server Plugin versions 4.5.1 and below. It allows attackers to inject malicious scripts into web pages viewed by users. The vulnerability requires user interaction, such as clicking a malicious link, to execute.

Detection Guidance

To detect this vulnerability, check the installed version of the WordPress OAuth Server Plugin. If it is 4.5.1 or below, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin directory for version details.

Immediately update the OAuth Server Plugin to version 4.5.2 or later. Enable auto-updates for the plugin if available. Remove or disable the plugin if updating is not possible.
