NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby4.0-fluentd-kubernetes-daemonset-1.19-kinesis package and not the ruby4.0-fluentd-kubernetes-daemonset-1.19-kinesis package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Prior to 1.19.3, the Fluentd out_http output plugin allows placeholders such as ${tag} in the endpoint configuration parameter, and if a placeholder value is derived from untrusted input an attacker can control the destination hostname of outbound HTTP requests and force requests to arbitrary internal services. This issue is fixed in version 1.19.3.
