{"id":"CVE-2020-12079","details":"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.","modified":"2026-07-08T16:28:51.668230Z","published":"2020-04-23T04:15:13.343Z","references":[{"type":"ADVISORY","url":"https://github.com/beakerbrowser/beaker/issues/1519"},{"type":"ADVISORY","url":"https://github.com/beakerbrowser/beaker/releases/tag/0.8.9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/beakerbrowser/beaker","events":[{"introduced":"0"},{"fixed":"33e79cc09fe40e1b9d60b96c77f5b52c80c6c0a0"}],"database_specific":{"cpe":"cpe:2.3:a:beakerbrowser:beaker:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.8.9"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["0.8.8","0.8.7","0.8.6","0.8.5","0.8.4","0.8.3","0.8.2","0.8.1","0.8.0","0.8.0-prerelease.9","0.8.0-prerelease.8","0.8.0-prerelease.7","0.8.0-prerelease.6","0.8.0-prerelease.5","0.8.0-prerelease.4","0.8.0-prerelease.2","0.8.0-prerelease.1","0.7.11","0.7.10","0.7.9","0.7.8","0.7.8-prerelease.2","0.7.8-prerelease.1","buildtest","0.7.7","0.7.6","0.7.5","0.7.3","0.7.2","0.7.1","0.7.0","0.6.1","0.6.0","0.5.2","0.5.1","0.5.0","0.4.2","0.4.1","0.4.0","0.3.7","0.3.2","0.3.1","0.3.0","0.2.0","in-browser-plugins-installer","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-12079.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
