URL Drag and Drop Local File Access Vulnerability in Firefox < 60

CVE-2018-5181 · MEDIUM Severity

AV:N/AC:L/AU:N/C:P/I:N/A:N

If a URL using the "file:" protocol is dragged and dropped onto an open tab that is running in a different child process the tab will open a local file corresponding to the dropped URL, contrary to policy. One way to make the target tab open more reliably in a separate process is to open it with the "noopener" keyword. This vulnerability affects Firefox < 60.
