Fastly is aware of an expected critical vulnerability the OpenSSL project is expected to disclose in the near future. We are studying the currently available information surrounding this vulnerability and do not currently believe that Fastly is vulnerable. We will continue to monitor as additional information is released and will provide our customers with more information as available.

Fastly has reviewed the initial notification from OpenSSL regarding CVE-2022-3786 and CVE-2022-3602. We have analyzed the versions of OpenSSL in use at Fastly, and verified that we do not use OpenSSL 3.x. Fastly and customer usage of Fastly services are not vulnerable to CVE-2022-3786 or CVE-2022-3602.
