high Tenable Self-Hosted Container Security Plugin ID 444010

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-44161)

Solution

Update the fluentd library and its related packages to version 1.19.3 or later.
