CVE-2022-34916: Improper Input Validation

August 22, 2022 (updated August 30, 2022)

Apache Flume versions 1.4.0 through 1.10.0 is vulnerable to a remote code execution (RCE) attack when a configuration uses a JMS Source with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI to allow only the use of the java protocol or no protocol.
