CVE-2026-116066

Firecrawl before 2.11.586 SSRF Protection Bypass via DNS Rebinding in Playwright Service

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.

firecrawl-mcp-server 3.20.2 Arbitrary Local File Read via filePath

firecrawl-mcp-server 3.20.2 contains an arbitrary local file read vulnerability in the firecrawl_parse tool that accepts unconstrained filePath arguments without directory containment validation. Attackers can supply absolute paths or directory traversal sequences to read sensitive files like credentials and environment variables, which are then uploaded and returned to the model context.

Firecrawl: Arbitrary file read via JSON Schema $ref expansion

Firecrawl turns entire websites into LLM-ready markdown or structured data. Prior to 2.11.32, a critical arbitrary file read vulnerability exists in Firecrawl's extraction functionality due to unsafe schema dereferencing of user-supplied JSON schemas in apps/api/src/lib/extract/helpers/dereference-schema.ts. The affected code invokes the json-schema-ref-parser dependency with default resolver settings, allowing external and local file references to be resolved during schema processing. An authenticated attacker can supply a malicious schema containing a $ref within default, const, or enum fields that are not traversed by AJV validation. By triggering a dereference error, file contents from the extract worker filesystem may be included in persisted error messages returned through the extraction API, enabling arbitrary file reads and SSRF against internal or external HTTP endpoints. This issue is fixed in version 2.11.32.

CVE-2025-57818

Firecrawl SSRF Vulnerability via malicious webhook

Firecrawl turns entire websites into LLM-ready markdown or structured data. Prior to version 2.0.1, a server-side request forgery (SSRF) vulnerability was discovered in Firecrawl's webhook functionality. Authenticated users could configure a webhook to an internal URL and send POST requests with arbitrary headers, which may have allowed access to internal systems. This has been fixed in version 2.0.1. If upgrading is not possible, it is recommend to isolate Firecrawl from any sensitive internal systems.

CVE-2026-32857

Firecrawl Playwright Service SSRF Protection Bypass via Missing Post-Redirect Validation

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.
