CVE-2022-42468: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

October 26, 2022 (updated October 27, 2022)

Apache Flume versions 1.4.0 through 1.10.1 is 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.
