NVD Description

Note: Versions mentioned in the description apply only to the upstream n8n-oci-entrypoint package and not the n8n-oci-entrypoint package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the GitHub Trigger generated a webhook secret but discarded it when GitHub returned HTTP 422 and the node reused an existing webhook. Workflow static data then retained webhookId without webhookSecret, and X-Hub-Signature-256 verification accepted deliveries without a stored secret. The affected logic includes packages/nodes-base/nodes/Github/GithubTriggerHelpers.ts and the 422 webhook reuse path. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
