CRITICAL 10.0EPSS 2.23%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
