DataHub is an open-source metadata platform. In versions of DataHub prior to 0.8.45 Session cookies are only cleared on new sign-in events and not on logout events. Any authentication checks using the AuthUtils.hasValidSessionCookie() method could be bypassed by using a cookie from a logged out session, as a result any logged out session cookie may be accepted as valid and therefore lead to an authentication bypass to the system.

Users are advised to upgrade. There are no known workarounds for this issue. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-083.
