Keap Official Opt-in Forms <= 1.0.11 - Admin+ Stored XSS

Published Jan 15, 2024 · Updated Jun 20, 2025 · Assigned by WPScan

Description

The Keap Official Opt-in Forms WordPress plugin through 1.0.11 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example, in multisite setup).
