CVE-2022-29380Public exploitNetwork attack vector

Stored script execution via unsanitized course SEO fields

Published May 25, 2022 · Updated Aug 3, 2024

Stored XSS in Academy-LMS 4.3 allows remote authenticated users to execute JavaScript in visitors' browsers via course SEO fields. The course manager's SEO submission stores attacker-supplied markup without neutralizing it, and the frontend course page renders the payload as executable content. Administrator access is required to plant the payload, and a visitor must open the affected course page; the demonstrated consequence is browser-context script execution.
