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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","score":5.6},"cwes":["CWE-668","CWE-693"],"references":["https://github.com/electron/electron/security/advisories/GHSA-56pc-6jqp-xqj8","https://github.com/electron/electron/security/advisories/GHSA-56pc-6jqp-xqj8"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15215","score":0.00683,"percentile":0.52544,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-56pc-6jqp-xqj8","url":"https://osv.dev/vulnerability/GHSA-56pc-6jqp-xqj8","summary":"Context isolation bypass in Electron","modified":"2026-07-08T06:00:17.374350172Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=8.0.0-beta.0 <8.5.2"],"fixed":["8.5.2"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=9.0.0-beta.0 <9.3.1"],"fixed":["9.3.1"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=10.0.0-beta.0 <10.1.2"],"fixed":["10.1.2"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=11.0.0-beta.0 <11.0.0-beta.6"],"fixed":["11.0.0-beta.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
