March 2016 PageSpeed Security Update.


All previously released versions of PageSpeed are vulnerable to CVE-2016-3626. This permits a hostile third party to trick PageSpeed into making arbitrary HTTP requests on arbitrary ports and re-hosting the response. If the machine running PageSpeed has access to services that are not otherwise available, this can reveal those resources. Additionally, this can be exploited for cross-site scripting.

Users are strongly encouraged to update immediately.
