Summary
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.
Risk Assessment
The risk involves potential access to internal network services and sensitive endpoints, which could lead to data exfiltration, privilege escalation, or further attacks on internal infrastructure.
Recommendation
Immediately update Firecrawl to a version later than 2.8.0 that includes a fix for the post-redirect SSRF protection gap. Until the update is applied, restrict access to the scraping service and implement additional network traffic filtering mechanisms.
Other vulnerabilities in Firecrawl
See all- CVE-2026-72904Critical
Firecrawl prior to version 2.11.32 contains a critical arbitrary file read vulnerability in its extraction functionality due to unsafe dereferencing of user-supplied JSON schemas. An authenticated attacker can supply a malicious schema with a $ref, allowing file reads from the extract worker filesystem and SSRF against internal or external HTTP endpoints.
- CVE-2026-116066Medium
Firecrawl before 2.11.586 contains a server-side request forgery vulnerability in the Playwright service SSRF proxy that allows attackers to bypass isInternalHost checks via DNS rebinding. Attackers controlling DNS for a scrape target can return a public address during validation and a private address at connect time, retrieving cloud metadata and internal resources through the scrape API.
Original NVD description (English source)
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.
