SCA: security update for fluent-plugin-opentelemetry (GHSA-2jc5-xhx8-qj6h)

medium Tenable Cloud Security Plugin ID 444007

Description

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

 - fluent-plugin-opentelemetry is a Fluentd input and output plugin for forwarding OpenTelemetry Protocol
 data. Prior to 0.5.3, the in_opentelemetry HTTP input read the entire incoming request body and
 decompressed payloads into memory without enforcing maximum size thresholds. When an OpenTelemetry
 ingestion endpoint was exposed to an untrusted network, an attacker could send an excessively large
 request or a highly compressed payload that expanded in memory. The resulting memory exhaustion could
 cause the operating system to terminate the Fluentd process, disrupting all log collection and forwarding
 on the affected node. This issue is fixed in version 0.5.3. (CVE-2026-44163)

Solution

Update the fluent-plugin-opentelemetry library and its related packages to version 0.5.3 or later.
