CVE-2025-71338
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 · uneditedFlowise contains a path traversal vulnerability in the /api/v1/document-store/loader/process endpoint that allows unauthenticated attackers to write arbitrary files to the filesystem. Attackers can exploit unsanitized fileName parameters with ../ sequences to overwrite critical files like package.json and achieve remote code execution when the application restarts.
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 · high confidenceFlowise contains an unauthenticated path traversal vulnerability in the /api/v1/document-store/loader/process endpoint where the fileName parameter lacks sanitization. Attackers can use ../ sequences to write arbitrary files to the filesystem, overwriting critical files like package.json to achieve remote code execution upon application restart.

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 installed Flowise versionRun 'npm list flowise' or check the version field in package.json located in the Flowise installation directoryAffected if The installed version is 3.1.3 or lower (any version <= 3.1.3)
-
Verify if document-store feature is in useCheck if any flows or configurations reference or utilize the document-store loader functionality, typically found in flow configuration files or the application's databaseAffected if Document-store loader feature is enabled or configured in any flow
-
Confirm API endpoint accessibilityAttempt a GET request to /api/v1/document-store/loader/process (or check reverse proxy/network access rules) to determine if the endpoint is reachable without authenticationAffected if The endpoint is exposed and accessible without authentication credentials
-
Inspect for unauthorized file modificationsReview file system integrity - check package.json, startup scripts, and configuration files in the Flowise installation directory for unexpected changes or new files, particularly those containing suspicious contentAffected if Any critical files (package.json, start scripts, config files) show unexpected modifications or contain unfamiliar code
A system is affected if it runs Flowise version 3.1.3 or lower AND has the document-store loader endpoint exposed 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 dataImplement strict input validation to reject path traversal sequences (../) in the fileName parameter, restrict file write operations to designated safe directories, and require authentication for the affected endpoint.
