AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N

Name of the Vulnerable Software and Affected Versions Customizr theme for WordPress versions up to, and including, 4.3.0

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the czr fn post fields save() function. This allows unauthenticated attackers to post fields via a forged request if they can trick a site administrator into performing an action such as clicking on a link.

Recommendations For versions up to, and including, 4.3.0, consider disabling the czr fn post fields save() function until a patch is available to prevent exploitation. Restrict access to areas of the site where this function is used to minimize the risk of attack.
