Sources and claim methodology

  • Source referencelists.apache.org
Upstream source description

The DRPC HTTP endpoint lets an authenticated client act as another user without applying the configured impersonation authorizer. An authenticated user can execute DRPC functions that are restricted to another user. Users are recommended to upgrade to version 3.2.0, which fixes the issue.
