Upgrade org.apache.hbase:hbase-thrift to version 2.5.15, 2.6.6, 3.0.0-beta-1 or higher.
Overview
org.apache.hbase:hbase-thrift is a HBase Thrift Server.
Affected versions of this package are vulnerable to Missing Authorization in the REST ScannerInstanceResource and Thrift HBaseServiceHandler scanner handling. An attacker can read rows from, or close, another user’s open scanner by reusing its scanner ID in a REST GET/DELETE request or Thrift scannerGet/scannerClose call. The vulnerable code binds scanner state to a shared server-side ID but does not verify that the caller owns that scanner before serving fetch or close operations. In deployments exposing the HBase REST or Thrift delegation services, this lets one authenticated user interfere with another user’s scan session and access data returned by that scanner.
