CVE-2019-11716
HIGHFirefox < 68.0 - Sandbox Bypass via Non-Enumerable window.globalThis
Title source: llmDescription
Until explicitly accessed by script, window.globalThis is not enumerable and, as a result, is not visible to code such as Object.getOwnPropertyNames(window). Sites that deploy a sandboxing that depends on enumerating and freezing access to the window object may miss this, allowing their sandboxes to be bypassed. This vulnerability affects Firefox < 68.
