{"id":"CVE-2020-15215","state":"PUBLISHED","title":"Context isolation bypass in Electron","description":"Electron before versions 11.0.0-beta.6, 10.1.2, 9.3.1 or 8.5.2 is vulnerable to a context isolation bypass. Apps using both `contextIsolation` and `sandbox: true` are affected. Apps using both `contextIsolation` and `nodeIntegrationInSubFrames: true` are affected. This is a context isolation bypass, meaning that code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions.","publishedAt":"2020-10-06T18:00:17.000Z","updatedAt":"2024-08-04T13:08:22.830Z","severity":{"score":5.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["electron electron"],"affected":[{"vendor":"electron","product":"electron","versions":[{"version":">= 8.0.0-beta.0, < 8.5.2","status":"affected"},{"version":">= 9.0.0-beta.0, < 9.3.1","status":"affected"},{"version":">= 10.0.0-beta.0, < 10.1.2","status":"affected"},{"version":">= 11.0.0-beta.0, < 11.0.0-beta.6","status":"affected"}]}],"references":["https://github.com/electron/electron/security/advisories/GHSA-56pc-6jqp-xqj8"],"weaknesses":["CWE-693","CWE-668"],"ingestedAt":"2026-10-29T19:46:36.523Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/15xxx/CVE-2020-15215.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-15215","state":"PUBLISHED","datePublished":"2020-10-06T18:00:17.000Z","dateUpdated":"2024-08-04T13:08:22.830Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2020-06-25T00:00:00.000Z"},"containers":{"cna":{"title":"Context isolation bypass in Electron","descriptions":[{"lang":"en","value":"Electron before versions 11.0.0-beta.6, 10.1.2, 9.3.1 or 8.5.2 is vulnerable to a context isolation bypass.
