Reflected XSS via unescaped type parameter
Published Mar 21, 2022 · Updated Aug 3, 2024
Reflected cross-site scripting in Squirrly SEO before 11.1.12 allows remote attackers to execute script via a crafted type parameter. An admin page inserts the type request parameter into an HTML attribute without context-appropriate output escaping. Exploitation requires a logged-in administrator to open the attacker-controlled request, after which the script runs in that administrator's browser context and can read or modify data available to the page.
