Answer in brief
CVE-2026-56775 records a Medium severity (CVSS 5.4) vulnerability in n8n - Incorrect OAuth Scope Validation in Evaluation Test Runs Endpoints. The current sources do not mark it as known exploited. The current feed maps n8n/n8n (generic), n8n/n8n (generic), n8n/n8n (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

n8n before 1.123.55, 2.25.7, and 2.26.2 contains an authorization vulnerability in three mutating evaluation test-run endpoints that authorize state-changing actions using the workflow:read scope instead of the action-appropriate workflow:execute scope. On instances using Advanced Permissions (Enterprise/Cloud) with projects and viewer roles, an authenticated user with the project:viewer role can start new evaluation test runs, cancel in-flight runs, and delete run records for workflows they only have read access to.
