CVE-2026-44163 (opens in a new tab)How to fix?
Upgrade fluent-plugin-opentelemetry to version 0.5.3 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the in_opentelemetry process. An attacker can cause excessive memory consumption by sending a large HTTP request or a highly compressed payload that decompresses to a very large size. This can result in the process being terminated by the operating system, disrupting log collection and forwarding capabilities.
Workaround
This vulnerability can be mitigated by restricting network access to the ingestion endpoint using firewall rules or deploying within a trusted network, and by placing a reverse proxy (such as Nginx) in front of the service to enforce strict limits on request and decompressed body sizes.
