CVE-2021-4384

Name of the Vulnerable Software and Affected Versions The WordPress Photo Gallery – Image Gallery plugin for WordPress versions up to, and including, 1.0.6

Description The issue is due to missing or incorrect nonce validation on the load images thumbnail() and edit gallery() functions, making it possible for unauthenticated attackers to edit galleries 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, 1.0.6, consider disabling the load images thumbnail() and edit gallery() functions as a temporary workaround until a patch is available. Restrict access to gallery editing features to minimize the risk of exploitation.
