In short

A compromised child process in Firefox can trick the parent process into opening malicious web content without proper verification, potentially leading to arbitrary code execution on the user's computer.

Technical detail

Insufficient validation of Prompt:Open IPC messages allows a sandboxed child process to manipulate the non-sandboxed parent process into opening attacker-controlled content. Combined with other vulnerabilities, this can lead to remote code execution. Affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
