Administrator-level stored XSS via unescaped settings
Published Sep 16, 2022 · Updated Aug 3, 2024
Stored XSS in WP Server Health Stats before 1.7.0 allows remote authenticated users with administrator access to execute script in browsers. The plugin stores the IP-API Pro key, Memcached host and port, and refresh interval without escaping them before page output. Administrator access is required to store a payload, and execution requires a user to load the affected settings output; the script runs in that user's browser context.
