Official Description
Subscriber Broken Access Control in Ultra Addons for WPForms <= 1.0.11 versions.
Technical Analysis
CVE-2026-39594 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
