Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Knox versions 0.2.0 through 0.11.0 (the gateway-provider-identity-assertion-common package) allow an authenticated user to impersonate another user when accessing WebHDFS through the gateway. An attacker needs only a valid account and a specially crafted URL, and can gain escalated privileges and unauthorized data access, though the activity is audit logged. Upgrade to Apache Knox 0.12.0, which contains the fix.
