| Titre | eiceblue spire-pdf-mcp-server 0.1.1 Path Traversal |
|---|
| Description | spire-pdf-mcp-server advertises PDF_FILES_PATH as the directory for managed PDF files. The server nonetheless resolves user-supplied paths with a helper that explicitly returns absolute paths unchanged and blindly joins relative paths to PDF_FILES_PATH without normalization or containment checks.
As a result, callers can escape the configured PDF directory with payloads such as ../../../../tmp/poc.pdf or /tmp/poc.pdf. Multiple exposed tools then operate on that escaped path, allowing arbitrary PDF creation, arbitrary PDF conversion to attacker-chosen output locations, and arbitrary reads of existing host PDFs that the service account can access. |
