DescriptionNVD

The Website LLMs.txt plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 8.2.6. This is due to the use of filter_input() without a sanitization filter and insufficient output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick an administrator into performing an action such as clicking on a link.

AnalysisAI

Reflected cross-site scripting (XSS) in the Website LLMs.txt WordPress plugin versions up to 8.2.6 allows unauthenticated attackers to inject arbitrary JavaScript via the 'tab' parameter due to improper use of filter_input() without sanitization and insufficient output escaping. Exploitation requires social engineering an administrator to click a malicious link, but once successful grants the attacker ability to execute scripts in the admin's browser session with access to sensitive WordPress functions and data.
