Reflected XSS via unescaped extension name
Published Jul 25, 2022 · Updated Aug 3, 2024
Reflected XSS in ThemeFuse Unyson before 2.7.27 allows context-dependent attackers to execute script via a crafted extension parameter. The display_extension_page() error path passes the attacker-controlled extension name through get_extension_title() and inserts it into HTML without escaping. An authenticated WordPress administrator must open the crafted wp-admin URL; the script then runs in the site's origin with access available to that browser session.
