Description
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.
