CVE-2021-25075Network attack vector

Stored XSS via unauthorized settings update

Published Feb 21, 2022 · Updated Aug 3, 2024

Stored XSS in WpDevArt Duplicate Page or Post before 1.5.1 allows remote authenticated users to inject script through plugin settings. The wpdevart_duplicate_post_parametrs_save_in_db AJAX action omits authorization, applies a flawed CSRF check, and stores settings without escaping untrusted input. Subscriber access or a forged request from a logged-in user is sufficient, and the stored script runs when the affected administrative content is viewed.
