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 · unedited
A vulnerability has been found in c-rick jimeng-mcp 1.10.0. Affected by this vulnerability is the function getFileContent/uploadCoverFile/generateImage/generateVideo of the file src/api.ts. The manipulation of the argument filePath leads to path traversal. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

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 confidence

Path traversal vulnerability in c-rick jimeng-mcp 1.10.0 allows remote attackers to access arbitrary files via manipulation of the filePath argument in multiple file-handling functions (getFileContent, uploadCoverFile, generateImage, generateVideo) in src/api.ts. The vulnerability exploits insufficient input validation on path traversal sequences like '../'.

MitigationImplement strict input validation and path sanitization on the filePath parameter, using path resolution functions to canonicalize paths and reject requests containing traversal sequences or attempting to access files outside allowed directories.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify jimeng-mcp installation and version
    Run 'npm list jimeng-mcp' or check package.json to confirm jimeng-mcp is installed and note its version number
    Affected if The installed version is exactly v1.10.0 or falls within the v1.10.x range
  2. Locate the vulnerable API file
    Check for the presence of src/api.ts in the jimeng-mcp installation directory
    Affected if The file src/api.ts exists and contains the functions getFileContent, uploadCoverFile, generateImage, or generateVideo
  3. Confirm API exposure
    Review the application's API server configuration to determine if endpoints calling the affected functions are exposed to network or remote access
    Affected if The vulnerable functions are exposed via API endpoints accessible to remote users
  4. Check for path traversal protection
    Inspect src/api.ts code to verify whether the filePath parameter in the affected functions includes sanitization logic that rejects '..' or '../' sequences
    Affected if No input validation or sanitization on the filePath parameter is found, or the code allows path traversal sequences through

A user is affected if jimeng-mcp v1.10.x is installed, the vulnerable API file exists with the affected functions, those functions are network-accessible, and no input validation blocks path traversal sequences in the filePath parameter.
