CVE intelligence and bounded remediation

CVE-2024-56800 — Firecrawl is a web scraper that allows users to extract the content of a webpage for a large language model

High CVSS 7.4

Firecrawl is a web scraper that allows users to extract the content of a webpage for a large language model. Versions prior to 1.1.1 contain a server-side request forgery (SSRF) vulnerability. The scraping engine could be exploited by crafting a malicious site that redirects to a local IP address. This allowed exfiltration of local network resources through the API. The cloud service was patched on December 27th, 2024, and the maintainers have checked that no user data was exposed by this vulnerability. Scraping engines used in the open sourced version of Firecrawl were patched on December 29th, 2024, except for the playwright services which the maintainers have determined to be un-patchable. All users of open-source software (OSS) Firecrawl should upgrade to v1.1.1. As a workaround, OSS Firecrawl users should supply the playwright services with a secure proxy. A proxy can be specified through the `PROXY_SERVER` env in the environment variables. Please refer to the documentation for instructions. Ensure that the proxy server one is using is setup to block all traffic going to link-local IP addresses.

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.
