Summary of Findings
The Log HTTP Requests plugin for WordPress is vulnerable to stored cross-site scripting (XSS) via logged HTTP requests in versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping.
The Log HTTP Requests WordPress plugin is affected by a stored XSS vulnerability that allows an attacker to gain unauthorized access to the WordPress Administrator account and carry out any action the admin was originally permitted to perform. It makes it possible for unauthenticated attackers who can trick a site’s administrator into performing an action like clicking on a link, or an authenticated user with access to a page that sends a request using user-supplied data via the server, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
