CVE-2023-2354
The CHP Ads Block Detector plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings reachable though an AJAX action in versions up to, and including, 3.9.4 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.47%). Track it; it rarely justifies an emergency change on its own.
Description
The CHP Ads Block Detector plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings reachable though an AJAX action in versions up to, and including, 3.9.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
