Summary

Apache Flume versions 1.4.0 through 1.10.1 are vulnerable to a remote code execution (RCE) attack when a configuration uses a JMS Source with an unsafe providerURL. This issue is fixed by limiting JNDI to allow only the use of the java protocol or no protocol.

Patch / fix

  • maven org.apache.flume.flume-ng-sources:flume-jms-source 1.11.0
  • Apache Software Foundation Apache Flume 1.11.0
