CVE-2026-12427: ARforms <= 7.2.4 - Unauthenticated Stored Cross-Site Scripting via 'description' Parameter
The ARforms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'description' parameter in all versions up to, and including, 7.2.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload is deserialized via maybeunserialize() when an administrator views the affected entry; if the attacker's array contains a 'referrer' key, the attacker-controlled pageurl and httpreferrer values are used as-is and rendered unescaped into the admin entry detail view.

Frequently Asked Questions
Who can exploit this issue, and what user interaction is required?
An unauthenticated attacker can submit a crafted value through the affected description parameter. The stored script executes when an administrator opens the affected entry detail view.
Which versions are affected?
All ARforms versions up to and including 7.2.4 are affected.
What conditions make the administrator view vulnerable?
The crafted serialized array must contain a referrer key. In that case, attacker-controlled page_url and http_referrer values are rendered without escaping in the administrator's entry detail view.
