CVE-2026-18501Network attack vector

Stored XSS via unescaped badge variable substitution

Published Aug 6, 2026 · Updated Aug 6, 2026

Stored XSS in AyeCode Ltd UsersWP 1.2.69 and earlier allows remote authenticated users to inject scripts through badge variables. In includes/helpers/pages.php, badge rendering substitutes unescaped user-writable profile values into %%input%% and named tokens, then decodes entities after substitution and passes the resulting HTML onward without output escaping. Subscriber access, an editable text field, and an administrator-configured badge using an affected token are required; viewing that badge executes the stored script in the visitor's browser.
