Description Doran Moppert 2019-06-21 00:00:59 UTC

Insufficient vetting of parameters passed with the `Prompt:Open`
IPC message between child and parent processes can result in the non-sandboxed
parent process opening web content chosen by a compromised child process.
When combined with additional vulnerabilities
this could result in executing arbitrary code on the user's computer.
