Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Beaker versions prior to 0.8.9

Description The issue 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.

Recommendations For versions prior to 0.8.9, update to version 0.8.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the Electron internal messaging API to minimize the risk of exploitation.
