Last modified

CVE-2020-12079 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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.. EPSS estimates a 2.23% chance of exploitation in the next 30 days.
