Official Description

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.

Risk Analysis

This critical vulnerability in Fluentd allows attackers to write or overwrite arbitrary files, potentially leading to remote code execution. The flaw, with a CVSS score of 9.8, arises from insufficient validation of the ${tag} placeholder in file configurations, enabling path traversal. This allows untrusted tags to dynamically construct malicious file paths.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable without authentication or user interaction.

Recommended Action

To mitigate this vulnerability, users should upgrade Fluentd to version 1.19.3 or later. Ensure that all inputs used in file path construction are properly sanitized and validated to prevent path traversal.

Technical Analysis

CVE-2026-44024 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
