CVE-2024-8182
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 Unauthenticated Denial of Service (DoS) vulnerability exists in Flowise version 1.8.2 leading to a complete crash of the instance running a vulnerable version due to improper handling of user supplied input to the “/api/v1/get-upload-file” api endpoint.
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 unauthenticated Denial of Service vulnerability in Flowise version 1.8.2 allows remote attackers to crash the entire service by sending specially crafted input to the /api/v1/get-upload-file API endpoint, which improperly handles user-supplied data leading to a complete instance crash.

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.
-
Determine if Flowise is installedCheck for Flowise installation by searching for flowise directories, running processes, or container images. Common locations: /opt/flowise, ~/flowise, or check running processes with 'ps aux | grep -i flowise' or Docker containers with 'docker ps'.Affected if Flowise software is present in the environment
-
Identify the installed Flowise versionCheck the package.json file in the Flowise installation directory for the version field, or run 'npm list flowise' if installed via npm. If running in Docker, check the image tag with 'docker images' or inspect the container metadata.Affected if The installed version is exactly 1.8.2
-
Verify the vulnerable API endpoint is exposedCheck if the /api/v1/get-upload-file endpoint is accessible by attempting a request to http://<host>:<port>/api/v1/get-upload-file, or review reverse proxy, firewall, and network access control configurations to determine if this endpoint is exposed to network traffic.Affected if The /api/v1/get-upload-file endpoint is reachable from the network (unauthenticated access is the default condition for this vulnerability)
-
Confirm the service is running without authentication protectionsReview Flowise configuration files (typically located in the installation directory under /src or as environment variables) to verify if authentication is enabled via AUTH_MODE or similar settings. By default, this CVE is exploitable without credentials.Affected if Authentication is not enabled or is set to a mode that allows unauthenticated access to the API endpoint
The environment is affected if Flowise version 1.8.2 is installed and the /api/v1/get-upload-file endpoint is accessible without authentication.
Generated from the published advisory. Verify against your own configuration.
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 Flowise to a patched version once available, or implement strict input validation and error handling on the /api/v1/get-upload-file endpoint to prevent crash-inducing inputs from causing service failure.
