Summary
CVE-2023-5243 is a vulnerability affecting the Login Screen Manager plugin for WordPress. The issue lies in the plugin's settings, which do not properly sanitize or escape user input. As a result, high-privilege users, including admins, can execute Stored Cross-Site Scripting attacks, bypassing the restriction of the unfiltered_html capability, even in multisite setups. This vulnerability poses a significant risk, potentially allowing attackers to inject malicious scripts into the WordPress site. Upgrading to the latest version of the plugin, which addresses this issue, is strongly recommended to ensure security.
