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 flaw has been found in eiceblue spire-pdf-mcp-server 0.1.1. This impacts the function get_pdf_path of the file src/spire_pdf_mcp/server.py of the component PDF File Handler. Executing a manipulation of the argument filepath can lead to path traversal. The attack can be launched remotely. The exploit has been published 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 the get_pdf_path function of spire-pdf-mcp-server 0.1.1 allows remote attackers to manipulate the filepath argument to access files outside the intended directory through directory traversal sequences (e.g., ../../../).

MitigationImplement strict input validation and sanitization on the filepath parameter, using canonical path resolution (os.path.realpath) and allowlist-based checks to ensure only intended directories can be accessed.

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. Identify if spire-pdf-mcp-server is installed
    Check installed packages or running services for spire-pdf-mcp-server. On Python environments: pip list | grep spire-pdf-mcp-server. On systems: check running processes or installed applications.
    Affected if The package or service is present and running on the system
  2. Verify the version number
    Run the package version check command appropriate to the installation method (pip show, npm list, or check the application metadata file). Compare the installed version to 0.1.1.
    Affected if The installed version matches exactly 0.1.1 or falls within the affected release range starting from 0.1.1
  3. Locate the get_pdf_path function exposure
    Search the codebase or application files for the get_pdf_path function definition. Check if it is exposed via an API endpoint, MCP tool, or RPC interface that accepts user-controlled filepath input.
    Affected if The get_pdf_path function is exposed and accessible to external input without validation
  4. Test for path traversal input acceptance
    If get_pdf_path is accessible, observe whether the filepath parameter accepts traversal sequences like ../../ or absolute paths outside the intended directory.
    Affected if The filepath parameter accepts and processes traversal sequences without rejection or path canonicalization checks

A user is affected if spire-pdf-mcp-server version 0.1.1 is installed and the get_pdf_path function is exposed to accept filepath input that can be manipulated with traversal sequences.

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.
