CVE-2020-36172

Name of the Vulnerable Software and Affected Versions: Advanced Custom Fields plugin version 5.8.11 and earlier

Description: The issue is related to the mishandling of string escaping in Select2 dropdowns, potentially leading to cross-site scripting (XSS). XSS is a type of attack where an attacker injects malicious code into a website, which is then executed by the user's browser. This can lead to unauthorized access to sensitive data or taking control of the user's session.

Recommendations: For versions prior to 5.8.12, update to version 5.8.12 or later to resolve the issue. As a temporary workaround, consider disabling the use of Select2 dropdowns in the Advanced Custom Fields plugin until a patch is applied. Restrict access to areas of the website that utilize the Advanced Custom Fields plugin to minimize the risk of exploitation.
