CVE-2021-25005Network attack vector

Stored XSS via unescaped plugin settings

Published Jan 17, 2022 · Updated Aug 3, 2024

Stored XSS in the SEUR Oficial WordPress plugin before 1.7.0 allows remote authenticated users to inject script through plugin settings. The affected settings handlers store values without sanitizing them and render those values without output escaping; public records do not name the fields. A high-privilege account is required, and execution requires another user to view the stored content even when unfiltered_html is disabled.
