CVE-2021-4391

Name of the Vulnerable Software and Affected Versions The Ultimate Gift Cards for WooCommerce plugin for WordPress versions up to, and including, 2.1.1

Description The issue is due to missing or incorrect nonce validation on the mwb wgm save post() function, making it possible for unauthenticated attackers to modify product gift card details via a forged request. This can happen if an attacker can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 2.1.1, update to a version that includes proper nonce validation for the mwb wgm save post() function to prevent Cross-Site Request Forgery attacks. As a temporary workaround, consider restricting access to the mwb wgm save post() function until a patch is available.
