NewCVE-2026-58661 (opens in a new tab)How to fix?
Upgrade Minimos:latest n8n to version 2.28.3-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream n8n package and not the n8n package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
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.
