CVE-2024-8181
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn Authentication Bypass vulnerability exists in Flowise version 1.8.2. This could allow a remote, unauthenticated attacker to access API endpoints as an administrator and allow them to access restricted functionality.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn authentication bypass vulnerability in Flowise version 1.8.2 allows remote, unauthenticated attackers to access API endpoints with administrator privileges, enabling them to bypass the authentication mechanism entirely and reach restricted functionality.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Flowise versionCheck the Flowise version by accessing the application UI footer, querying the /api/v1/version or /api/version endpoint, reviewing startup logs, or inspecting the package.json file in the installation directoryAffected if The installed version is exactly 1.8.2
-
Verify API endpoint authentication statusAttempt to access restricted API endpoints (such as /api/v1/flows, /api/v1/credentials, or /api/v1/assistants) without providing any credentials using a tool like curl: curl -s http://<flowise-host>:<port>/api/v1/flowsAffected if The API endpoints return valid data or successful responses without requiring authentication tokens
-
Check if admin-level operations are reachable unauthenticatedSend requests to administrative endpoints like GET /api/v1/credentials or POST /api/v1/flows without Authorization headers, observing whether the operations succeedAffected if Administrative operations execute successfully without authentication credentials being provided
-
Review authentication middleware configurationExamine the Flowise configuration files (config.yaml, .env, or similar) for FLOWISE_AUTH_ENABLED or similar authentication flags, and check if authentication middleware is properly applied to API routesAffected if Authentication is disabled in the configuration or authentication middleware is missing from API route definitions
The environment is affected if Flowise version 1.8.2 is installed AND API endpoints are accessible without authentication credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade from Flowise 1.8.2 to a patched version and review authentication configuration to ensure all API endpoints require proper credential validation.
