SCA: security update for fluentd (GHSA-44hj-4m45-frj3)

critical Tenable Cloud Security Plugin ID 444012

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, Fluentd allows dynamically constructing file paths using the ${tag}
 placeholder, and insufficient validation of ${tag} in file configurations such as the path parameter of
 the out_file plugin allows attackers sending untrusted tags containing path traversal characters to write
 or overwrite arbitrary files and potentially achieve remote code execution. This issue is fixed in version
 1.19.3. (CVE-2026-44024)

Solution

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