What is CVE-2026-81404?

The IPGP Visitors Origin plugin for WordPress fails to properly sanitize and escape user input before including it in the HTTP response. This oversight allows unauthenticated attackers to execute malicious scripts by tricking users into submitting crafted requests. As a result, an attacker could potentially hijack user sessions or manipulate web pages viewed by victims, exposing them to further attacks.

Affected Version(s)

IPGP Visitors Origin 1.3 < 1.6
