CVE-2026-76403

Name of the Vulnerable Software and Affected Versions Splunk Connect for Kafka versions prior to 2.2.7

Description An unauthenticated user positioned in the network path can read or modify data sent from the connector when Kerberos authentication is used with the Hypertext Transfer Protocol (HTTP) Event Collector in Splunk Enterprise. This occurs because the Kerberos authentication path fails to apply the configured certificate validation options during the construction of the HTTP client.

Recommendations Update Splunk Connect for Kafka to version 2.2.7 or later.
