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.

GHSA-pq6c-vh67-xpm3 — n8n: Log Streaming Event Destinations Decrypt Generic-Auth Credentials Without Ownership Check

2026-10-03T19:02:15.816605+00:00

Affected: npm: n8n

## 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: - Restrict n8n instance access to fully trusted users only. - Audit and revoke any custom global roles that carry Log Streaming scopes (`eventBusDestination:create`, `eventBusDestination:test`, etc.), limiting those scopes to fully trusted users only. - Review existing Log Streaming event destinations for unexpected webhook URLs and remove any that are not recognized, then rotate any credentials that may have been referenced.

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