Stored XSS via unescaped heading tag setting
Published Jun 26, 2024 · Updated Aug 1, 2024
Stored XSS in Backup For WP Easy Table of Contents before 2.0.66 allows remote authenticated users to run scripts via saved settings. The plugin stores the ez-toc-settings[heading_text_tag] value without adequate sanitization and emits it into generated table-of-contents markup without escaping. An editor or another high-privilege account can inject the payload even when unfiltered_html is disabled, and execution occurs when a user views affected content.
