CyberRota Analysis
AI-GeneratedThe vulnerability affects the logstash source of Vector, allowing unauthenticated remote peers to exploit unlimited nested compression depth, leading to a stack exhaustion that can crash the process. This results in halted log ingestion for all tenants on a shared pipeline, significantly impacting observability and data collection. Organizations using versions 0.15.0 to 0.57.0 should prioritize upgrading to version 0.57.0 to mitigate this high-severity risk.

Original NVD Description
Vector is a high-performance observability data pipeline. From 0.15.0 until 0.57.0, the logstash source feeds each decompressed frame back into its decoder without limiting nested compression depth. An unauthenticated remote peer that can reach the default 0.0.0.0:5044 listener can send many nested compressed frames, causing recursive decoding that exhausts the worker thread stack and aborts the process. The same nested construction amplifies decompressed input, and process termination can halt log ingestion for every tenant on a shared pipeline. This issue is fixed in version 0.57.0.
