I don&#x27;t see how the CSO&#x27;s response makes sense for Facebook&#x27;s security interests. As CSO, it is in your interest to allow a researcher to exploit an RCE to its furthest. Otherwise, you would only ever allow researchers to inoculate your outest layer of protection, while leaving any inner level untested and thus less secure.<p>If indeed only credentials and technical information were obtained, all aimed at finding more security issues, Facebook should be thankful for finding all the vulnerabilities across all their security layers.
