CyberRota Analysis
AI-GeneratedThe fluent-plugin-opentelemetry prior to version 0.5.3 is vulnerable to memory exhaustion due to its handling of incoming HTTP requests without enforcing maximum size limits. An attacker could exploit this by sending oversized or highly compressed payloads, potentially causing the Fluentd process to terminate and disrupting log collection and forwarding. Organizations using this plugin, especially those exposing ingestion endpoints to untrusted networks, should prioritize upgrading to version 0.5.3 to mitigate this risk.

Original NVD Description
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.
