Technical details

An open redirect vulnerability (CWE-601) exists in the login page's handling of the redirect query parameter, which is improperly sanitized. An unauthenticated attacker can craft a URL with an external redirect parameter that, when clicked by a logged-in user, redirects them outside the Coder application. The attack requires user interaction (clicking the malicious link) but no authentication or special privileges.
