CVE-2023-6941 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. 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).. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
