CVE-2022-42468Network attack vector

Remote code execution via unsafe JNDI provider URL

Published Oct 26, 2022 · Updated May 7, 2025

JNDI injection in Apache Flume 1.4.0 through 1.10.1 allows remote attackers to execute code through an unsafe JMS Source providerURL. JMSSource passes the configured providerUrl to a JNDI InitialContext lookup without validating the name, allowing deserialization of data from an untrusted provider. Exploitation requires a JMS Source configured with an unsafe providerURL; successful code runs in the Flume agent process.
