Administrator-level stored XSS via unescaped post-type settings
Published May 15, 2025 · Updated May 20, 2025
Stored XSS in Auto Prune Posts before 3.0.0 allows remote authenticated users to inject script through post-type settings. The plugin stores post-type setting values without sanitizing them and renders those values in an administrative page without output escaping. Administrator privileges are required, and exploitation still works when unfiltered_html is disabled, causing the script to run when another user views the affected page.
