What is CVE-2021-24950?
CVE-2021-24950 is a medium-severity unsafe deserialization vulnerability in Unknown Insight Core, published on 14 Mar 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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
