Unauthenticated stored XSS via unsanitized AJAX values
Published Jun 24, 2026 · Updated Jun 24, 2026
Stored XSS in Repute InfoSystems ARForms 7.1.3 and earlier allows remote attackers to inject scripts through incomplete form entries. The arf_save_incomplete_form_data AJAX action persists the value parameter without sufficient input sanitization, and the Partial Filled Form Entries page renders it without adequate output escaping. No authentication is required to plant the payload; execution occurs in an administrator's browser when that administrator views the stored partial entry, enabling actions available to that session.
