CVE-2026-35104 · Other
NO FIX YET
The AION user registration page takes a 'redirect' query parameter and sends the user there after signup without checking it. A crafted registration link can therefore send a user to an attacker-chosen external site, which is useful for phishing.

It checks your repository and tells you if you’re affected, with the fix.
Teams that run HCL AION with self-service user registration enabled are exposed, since the flaw sits on the Signup component. The sources do not say which AION versions are affected or whether registration must be open to the public. Deployments where sign-up is closed or limited to administrators are likely less exposed, but the sources do not confirm this.
Not affected if signup-disabled

Unknown from the sources.
No fix yet, per the sources.
HCL AION is affected by an open redirect vulnerability on the user registration page (Signup component). The redirect performed after registration used the value of the 'redirect' query parameter without validation, so a crafted registration link could send a user to an untrusted external site. This may be used in phishing attacks, potentially resulting in unintended behavior or security impact under certain conditions.
