It checks your repository and tells you if you’re affected, with the fix.
Teams that run HCL AION 2.6.0 with its GenAI web interface are affected. The UserContext session-handling code (line 89) redirects to the login URL set in the build variable NEXT_PUBLIC_LOGIN_URL without validating the destination, so it can be abused for phishing and needs a user to click (CVSS 4.7). HCL's bulletin names V 2.6.0 as affected and 2.8.0 as fixed; it is silent on older versions. Teams not running AION can skip it. It is one of several sibling open-redirect CVEs fixed in the same bulletin (35102-35105, 35107).
Not affected if unknown

2.6.0 as affected and 2.8.0 as the fix; it does not say whether versions older than 2.6.0 are affected, so treat them as unknown and ask HCL supportHCL AION is affected by an open redirect vulnerability in the session-handling logic of the GenAI web interface (UserContext component, line 89). A second redirect to the login page in this component used a URL taken from build configuration (NEXT_PUBLIC_LOGIN_URL) without validating the redirect destination. This may be used in phishing attacks, potentially resulting in unintended behavior or security impact under certain conditions.
