high Tenable Cloud Security Plugin ID 447895

Description

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

 - n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the OAuth Dynamic Client
 Registration endpoint bounded redirect_uris but accepted arbitrarily large client_name and grant_types
 values. An unauthenticated remote caller could repeatedly persist oversized values in oauth_clients and
 exhaust database storage. The affected validation is in packages/cli/src/modules/oauth-server/oauth-
 server.service.ts, including MAX_CLIENT_NAME_LENGTH and MAX_GRANT_TYPES. This issue is fixed in versions
 2.37.7 and 2.38.2. (CVE-2026-86075)

Solution

Update the n8n library and its related packages to version 2.37.7 or later.
