Name of the Vulnerable Software and Affected Versions Live Composer versions prior to 2.1.23

Description Insufficient sanitization and escaping of custom post type slug settings used in front-end links allows high-privilege users, such as administrators, to execute Stored Cross-Site Scripting (XSS) attacks. This issue persists even when the unfiltered html capability is disabled, which is common in multisite configurations. Stored XSS occurs when a malicious script is permanently stored on the target server and served to other users.

Recommendations Update Live Composer to version 2.1.23 or later.
