Technical details
The vulnerability is an open redirect flaw in Helix Ultimate versions before 2.2.10, where return redirect parameters accept arbitrary Base64-encoded strings without validating whether the decoded target is an internal site URL. The vulnerable code fails to properly use Uri::isInternal() to verify redirect destinations. An unauthenticated attacker can craft a malicious URL containing a Base64-encoded external domain in the return parameter, which the application will decode and redirect users to without validation. When a user clicks the crafted link, they are silently redirected to the attacker's website. The vulnerability has been patched in version 2.2.10 as of August 2026.
