# CVE-2026-35104: HCL AION is affected by multiple security vulnerabilities.

Status: published. Published: 2026-11-06. Updated: 2026-11-06.

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.
