# CVE-2022-0661: Ad Injection \<= 1.2.0.19 - Admin+ Stored Cross-Site Scripting & RCE

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2022-04-18 · Updated: 2024-08-02

## Affected

- Unknown Ad Injection: 1.2.0.19 only

## Description

The Ad Injection WordPress plugin through 1.2.0.19 does not properly sanitize the body of the adverts injected into the pages, allowing a high privileged user (Admin+) to inject arbitrary HTML or javascript even with unfiltered_html disallowed, leading to a stored cross-site scripting (XSS) vulnerability. Further it is also possible to inject PHP code, leading to a Remote Code execution (RCE) vulnerability, even if the DISALLOW_FILE_EDIT and DISALLOW_FILE_MOD constants are both set.

## What to do
