Submit #810105: H2O-3 latest arbitrary local file disclosureinfo

TitleH2O-3 latest arbitrary local file disclosure
DescriptionH2O-3 exposes the unauthenticated ImportFiles API in a way that allows attacker-controlled local filesystem paths to be imported as frames. Because path restrictions rely on an incomplete blacklist and do not enforce a safe import directory, an unauthenticated attacker can import readable local files and retrieve their contents through the Frames API, resulting in arbitrary local file disclosure.
