CVE-2022-0661

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.
