CVE-2021-24950 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. The Insight Core WordPress plugin through 1.0 does not have any authorisation and CSRF checks in the insight_customizer_options_import (available to any authenticated user), does not validate user input before passing it to unserialize(), nor sanitise and escape it before outputting it in the response. As a result, it could allow users with a role as low as Subscriber to perform PHP Object Injection, as well as Stored Cross-Site Scripting attacks. EPSS estimates a 0.52% chance of exploitation in the next 30 days.
