CVE-2026-86993: CWE-862: Missing Authorization in n8n-io n8n
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.
AI Analysis
Technical Summary
n8n versions before 1.123.76, 2.37.7, and 2.38.2 contain a missing authorization (CWE-862) vulnerability in the Log Streaming event destination module. A user with a custom global role that includes Log Streaming scopes can select and decrypt HTTP credentials from other projects without verifying ownership, potentially exposing sensitive secrets to attacker-controlled endpoints. The vulnerability affects the authorization boundary in packages/cli/src/modules/log-streaming.ee/destinations/destination-credentials-access.ts and specifically the credential:read scope. This flaw is resolved in the fixed versions 1.123.76, 2.37.7, and 2.38.2.
Potential Impact
An attacker with a custom global role that includes Log Streaming scopes can access and decrypt credentials from other projects, potentially exposing sensitive secrets to external endpoints. This compromises the confidentiality of credentials within the n8n platform. The CVSS 4.0 score is 5.9 (medium severity), reflecting network attack vector, low attack complexity, and partial privileges required.
Mitigation Recommendations
Upgrade n8n to version 1.123.76, 2.37.7, or 2.38.2 or later, where this missing authorization vulnerability is fixed. No other mitigation is indicated by the vendor advisory. Patch status is not explicitly stated but the description confirms the issue is fixed in these versions.
