What is CVE-2026-12427?

The ARforms plugin for WordPress is susceptible to a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping in the 'description' parameter. This allows unauthenticated attackers to inject malicious web scripts that execute when any user accesses the compromised page. The flaw is particularly concerning because when an administrator reviews the affected entries, the injected payload is deserialized, permitting the attacker to manipulate values rendered unescaped in the admin view.

Affected Version(s)

ARforms 0 <= 7.2.4
