CVE-2025-57818 — Firecrawl turns entire websites into LLM-ready markdown or structured data

Medium CVSS 6.3

Firecrawl turns entire websites into LLM-ready markdown or structured data. Prior to version 2.0.1, a server-side request forgery (SSRF) vulnerability was discovered in Firecrawl's webhook functionality. Authenticated users could configure a webhook to an internal URL and send POST requests with arbitrary headers, which may have allowed access to internal systems. This has been fixed in version 2.0.1. If upgrading is not possible, it is recommend to isolate Firecrawl from any sensitive internal systems.

Matched remediation archetype

Server-side request forgery and unintended proxying

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
