Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-601.
Summary
HoloViz Panel from 1.2.2 before 1.9.0 contains an open redirect (CWE-601) in its login handling. The next query parameter is not validated, so a remote attacker can craft a login link that sends the user to an external site after a successful login. The victim must follow the crafted link for the redirect to occur.

Description from the CNA
HoloViz Panel from 1.2.2 before 1.9.0 contains an open redirect vulnerability in panel/auth.py that allows remote attackers to redirect users by supplying an unvalidated next query parameter. BasicLoginHandler and PasswordLoginHandler store the parameter in a next_url cookie, so crafted login links send victims to attacker-controlled external sites after successful login.
