# CVE-2021-24950: Insight Core \<= 1.0 - Subscriber+ PHP Object Injection & Stored XSS

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2022-03-14 · Updated: 2024-08-03

## Affected

- Unknown Insight Core: 1.0 only

## 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
