Advisory details

Impact

A log streaming event destination may reference a generic HTTP credential, and the destination resolved and decrypted whichever credential it named without checking that the caller had access to it. A user holding a custom global role scoped to Log Streaming operations could therefore name a credential belonging to another project and have its decrypted secret sent to an endpoint they controlled. The patch applies the standard credential access check when a destination resolves its credential.

Patches

The issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. Users should upgrade to one of these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
