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.
Analysis
Firecrawl's Playwright scraping service through version 2.8.0 permits attackers to bypass SSRF protections and access internal network resources by exploiting a validation gap in redirect handling. Unauthenticated remote attackers can supply externally valid URLs that redirect to restricted internal endpoints, as network policy checks apply only to the initial request and not subsequent redirect destinations. …

Remediation
Within 24 hours: Identify all systems running Firecrawl version 2.8.0 or earlier and assess whether they process untrusted URLs or are accessible to external users. Within 7 days: Implement network segmentation to restrict Firecrawl's outbound access and apply WAF rules to block suspicious redirect patterns; review recent access logs for evidence of exploitation. …
