SCA: security update for n8n (GHSA-pr9r-gxgp-9rm8)

medium Tenable Cloud Security Plugin ID 428286

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - n8n is a workflow automation platform. Prior to version 1.99.0, there is a denial of Service vulnerability
 in /rest/binary-data endpoint when processing empty filesystem URIs (filesystem:// or filesystem-v2://).
 This allows authenticated attackers to cause service unavailability through malformed filesystem URI
 requests, effecting the /rest/binary-data endpoint and n8n.cloud instances (confirmed HTTP/2 524 timeout
 responses). Attackers can exploit this by sending GET requests with empty filesystem URIs (filesystem://
 or filesystem-v2://) to the /rest/binary-data endpoint, causing resource exhaustion and service
 disruption. This issue has been patched in version 1.99.0. (CVE-2025-49595)
