CVE-2020-12079

Beaker before 0.8.9 allows a sandbox escape, enabling system access and code execution. This occurs because Electron context isolation is not used, and therefore an attacker can conduct a prototype-pollution attack against the Electron internal messaging API...

Internet Bug Bounty: Context isolation bypass via nested unserializable return value

A vulnerability was discovered in Electron that allowed for a bypass of context isolation. This meant that code running in the main world context in the renderer could access the isolated Electron context and perform privileged actions. The vulnerability was fixed in versions 25.0.0-alpha.2,...
