Description

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, a Log Streaming event destination could reference a generic HTTP credential and decrypt whichever credential ID it named without an ownership check. A user with a custom global role carrying Log Streaming scopes could select a credential belonging to another project and send its decrypted secret to an attacker-controlled endpoint. The affected authorization boundary is packages/cli/src/modules/log-streaming.ee/destinations/destination-credentials-access.ts and the credential:read scope. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
