What is CVE-2026-32857?
CVE-2026-32857 is a high-severity server-side request forgery vulnerability in Firecrawl, published on 26 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
