Description

n8n before 1.123.85, 2.43.5, and 2.44.1 contains a regular expression denial of service vulnerability that allows authenticated members to block the event loop via crafted glob patterns. Attackers who can create and run workflows can submit a wildcard-heavy File(s) Selector pattern causing exponential backtracking, making the UI, API, webhooks, and health checks unresponsive until restart.
