WP-Recall WordPress Plugin Stored Cross-Site Scripting Vulnerability for Admin Users

A stored cross-site scripting vulnerability has been identified in the WP-Recall WordPress plugin, affecting versions prior to 16.26.12. The issue arises because the plugin fails to properly sanitize and escape certain settings. This flaw enables high-privilege users, such as administrators, to execute stored cross-site scripting attacks, even in environments where the unfiltered_html capability is restricted, such as multisite setups.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user.
