Stored XSS via unescaped quality setting

Published Oct 10, 2022 · Updated Aug 3, 2024

Stored XSS in reSmush.it Image Optimizer before 0.4.6 allows remote authenticated users to run script in another user's browser. The resmushit_qlty setting accepts crafted input through WordPress's options.php endpoint and is rendered without sanitization or output escaping. An administrator-level account is required, and exploitation remains possible when WordPress denies the unfiltered_html capability.
