Local file disclosure via unconstrained parse path
Published Sep 4, 2026 · Updated Sep 4, 2026
Path traversal in Firecrawl MCP Server 3.24.0 and earlier allows attackers to read local files through crafted filePath values. The firecrawl_parse tool resolves the supplied path and passes it directly to readFile without rejecting absolute paths or traversal outside an allowed directory. Reachability requires control of a parse tool call in a local or self-hosted deployment; retrieved contents are uploaded to the configured Parse API and returned to the model context.
