{"id":"CVE-2020-15174","state":"PUBLISHED","title":"Unpreventable top-level navigation in Electron","description":"In Electron before versions 11.0.0-beta.1, 10.0.1, 9.3.0 or 8.5.1 the `will-navigate` event that apps use to prevent navigations to unexpected destinations as per our security recommendations can be bypassed when a sub-frame performs a top-frame navigation across sites. The issue is patched in versions 11.0.0-beta.1, 10.0.1, 9.3.0 or 8.5.1 As a workaround sandbox all your iframes using the sandbox attribute. This will prevent them creating top-frame navigations and is good practice anyway.","publishedAt":"2020-10-06T17:35:13.000Z","updatedAt":"2024-08-04T13:08:22.398Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["electron electron"],"affected":[{"vendor":"electron","product":"electron","versions":[{"version":">= 8.0.0-beta.0, < 8.5.1","status":"affected"},{"version":">= 9.0.0-beta.0, < 9.3.0","status":"affected"},{"version":">= 10.0.0-beta.0, < 10.0.1","status":"affected"}]}],"references":["https://github.com/electron/electron/security/advisories/GHSA-2q4g-w47c-4674","https://github.com/electron/electron/commit/18613925610ba319da7f497b6deed85ad712c59b"],"weaknesses":["CWE-693","CWE-20"],"ingestedAt":"2026-10-29T19:46:36.523Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/15xxx/CVE-2020-15174.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-15174","state":"PUBLISHED","datePublished":"2020-10-06T17:35:13.000Z","dateUpdated":"2024-08-04T13:08:22.398Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2020-06-25T00:00:00.000Z"},"containers":{"cna":{"title":"Unpreventable top-level navigation in Electron","descriptions":[{"lang":"en","value":"In Electron before versions 11.0.0-beta.1, 10.0.1, 9.3.0 or 8.5.1 the `will-navigate` event that apps use to prevent navigations to unexpected destinations as per our security recommendations can be bypassed when a sub-frame performs a top-frame navigation across sites.
