Duplicate Advisory: Authenticated Users Can Exhaust Temporary Disk Storage via Data-Table File Uploads

Original Description

n8n before 2.28.0 (and before 1.123.58 on the 1.x branch) contains a disk space exhaustion vulnerability in the data-table file upload endpoint. The per-request quota check does not account for files already written to the shared temporary directory, allowing an authenticated user to repeatedly upload files that accumulate on disk until the periodic cleanup runs, potentially exhausting available disk space on the host.
