CVE-2026-85171

medium

n8n before 1.123.73, 2.35.4, and 2.36.2 contains a credential exposure vulnerability in the Strapi, SeaTable, and Mailcheck nodes.

Vendor / product: N8n — n8n

n8n before 1.123.73, 2.35.4, and 2.36.2 contains a credential exposure vulnerability in the Strapi, SeaTable, and Mailcheck nodes. These nodes send their decrypted credentials to the authentication endpoint via the raw legacy HTTP helper outside any error handling, causing the plaintext secret to be persisted in execution error data. Any authenticated user can read the plaintext secret from their own execution through the REST API, bypassing the blank-value redaction enforced by the credentials API.
