Administrator-session script execution via unescaped field caption
Published Jun 30, 2026 · Updated Jun 30, 2026
Stored XSS in WPChill Kali Forms before 2.4.13 allows remote authenticated users to run JavaScript in an administrator's session. The form-entries list table emits a field caption as a column header without sanitization or escaping, while the duplicate-post action lacks a capability check. Contributor-level access can therefore publish a crafted form, but exploitation still requires an administrator to open its entries screen.
