Impact
A pen-testing team has discovered an SSRF vulnerability in Firecrawl. The scraping engine could be exploited by crafting a malicious site that redirects to a local IP address. This allowed exfiltration of local network resources through the API.
Patches
-
The cloud service was patched on December 27th and we have checked that no user data was exposed by this vulnerability.
-
Scraping engines used in the open sourced version of Firecrawl were patched on December 29th except for the playwright services which we have determined to be un-patchable. See the workaround section for instructions on how to secure the playwright services.
We strongly recommend that all of our OSS users update to the latest version of Firecrawl (v1.1.1 at this time).
Workarounds
We strongly recommend that OSS users supply the playwright services with a secure proxy. A proxy can be specified through the PROXY_SERVER env in the environment variables. Please refer to the documentation for instructions.
Please ensure that the proxy server you are using is setup to block all traffic going to link-local IP addresses.
