CVE-2025-7431 is a stored cross-site scripting vulnerability in the Knowledge Base plugin for WordPress affecting all versions up to and including 2.3.1. The flaw is caused by insufficient input sanitization and output escaping of the plugin slug setting. An authenticated attacker with administrator-level access can inject arbitrary JavaScript or other web script payloads into stored content associated with that setting. The payload executes when a user accesses a page containing the injected content. According to the available information, the issue is limited to WordPress multisite installations and to installations where the unfiltered_html capability has been disabled.

This repository documents a proof-of-concept (PoC) exploit for CVE-2025-7431, a stored cross-site scripting (XSS) vulnerability in the Knowledge Base plugin for WordPress (versions 2.3.1 and below). The exploit requires an authenticated attacker (Contributor or Administrator) to inject a malicious shortcode payload into the plugin's 'Slug' field via the admin dashboard. When another user accesses the 'All Articles' view, the injected JavaScript executes, leading to persistent XSS. The repository contains two markdown files (README.md and report.md) that describe the vulnerability, exploitation steps, and security impact. No executable code is present; the PoC is a manual exploitation guide with a sample payload. The main attack vector is authenticated web access to the WordPress admin panel, and the exploit targets the Knowledge Base plugin's settings interface.
