Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Pulsar's Kafka connectors (pulsar-io-kafka and pulsar-io-kafka-connect-adaptor) log sensitive configuration properties in plain text in application logs in versions before 3.0.11, 3.3.6 and 4.0.4, with affected ranges including 3.3.0 to before 3.3.6 and 4.0.0 to before 4.0.4. An attacker who can read those application logs could obtain Apache Kafka credentials. Upgrade to 3.0.11, 3.3.6, 4.0.4 or a newer release, matching your version line.
