Name of the Vulnerable Software and Affected Versions NEX-Forms – Ultimate Forms Plugin for WordPress versions prior to 9.2.3

Description An authorization bypass exists because the plugin fails to properly verify if a user is authorized to perform specific actions. This allows unauthenticated attackers to overwrite the saved admin email, saved user email, and saved user email address fields of form entries belonging to other users. Consequently, the site can be manipulated to send attacker-controlled email content to recipient addresses chosen by the attacker.

Recommendations Update NEX-Forms – Ultimate Forms Plugin for WordPress to version 9.2.3 or later.
