CVE-2026-32857 — Firecrawl security vulnerability

High CVSS 8.6

Firecrawl version 2.8.0 and prior contain a server-side request forgery (SSRF) protection bypass vulnerability in the Playwright scraping service where network policy validation is applied only to the initial user-supplied URL and not to subsequent redirect destinations. Attackers can supply an externally valid URL that passes validation and returns an HTTP redirect to an internal or restricted resource, allowing the browser to follow the redirect and fetch the final destination without revalidation, thereby gaining access to internal network services and sensitive endpoints. This issue is distinct from CVE-2024-56800, which describes redirect-based SSRF generally. This vulnerability specifically arises from a post-redirect enforcement gap in implemented SSRF protections, where validation is applied only to the initial request and not to the final redirected destination.

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.
