Memory exhaustion in MinIO S3 Select (RELEASE.2018-08-18T03-49-57Z through RELEASE.2025-12-20T04-58-37Z) allows authenticated users with s3:PutObject and s3:GetObject permissions to crash the server by uploading CSV files lacking newline characters. The vulnerable CSV reader buffers entire lines into memory without size limits, enabling attackers to trigger out-of-memory conditions. A ~2 MB compressed CSV can decompress to gigabytes without newlines, causing denial of service. No public exploit identified at time of analysis.
