Name of the Vulnerable Software and Affected Versions WPUpper Share Buttons plugin for WordPress versions up to, and including, 3.51

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the save custom css request function. This allows unauthenticated attackers to inject custom CSS and modify a site by tricking a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 3.51, update to a version that includes the fix for the missing or incorrect nonce validation in the save custom css request function. As a temporary workaround, consider restricting access to the save custom css request function until a patch is available.
