{"id":"GHSA-j84w-jfhq-vhvj","summary":"Electron: File and HTTP protocol handlers allow cross-origin reads without corsEnabled","details":"### Impact\n\nResponses served through `protocol.registerFileProtocol` or `protocol.registerHttpProtocol` for a custom scheme registered with `supportFetchAPI: true` but without `corsEnabled: true` could be read cross-origin by web content. This completes the fix for CVE-2026-70604.\n\nApps are only affected if they register such a scheme, serve it through one of those handlers, and load untrusted content. Apps that set `corsEnabled: true`, or that do not load untrusted content, are not affected.\n\n### Workarounds\n\nSet `corsEnabled: true` on the scheme, or do not load untrusted content in windows that can reach it.\n\n### Fixed Versions\n\n* `44.0.0-beta.5`\n* `43.4.1`\n* `42.9.2`\n* `41.10.6`\n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)","aliases":["CVE-2026-102675"],"modified":"2026-09-29T18:15:05.563347930Z","published":"2026-09-29T18:04:24Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-346"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-09-29T18:04:24Z"},"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-j84w-jfhq-vhvj"},{"type":"WEB","url":"https://github.com/electron/electron/commit/4d2784cc8592471ee2276235b8c2a03efddf937d"},{"type":"WEB","url":"https://github.com/electron/electron/commit/80178e4631cb2f6a5e42f8e793b2ae9624e78a0d"},{"type":"WEB","url":"https://github.com/electron/electron/commit/c595b05976e7a885465b043d17e00a92fc3c3397"},{"type":"WEB","url":"https://github.com/electron/electron/commit/ef75c4b98caaa3ebc615f1eba302027028ee04d2"},{"type":"PACKAGE","url":"https://github.com/electron/electron"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v41.10.6"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v42.9.2"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v43.4.1"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v44.0.0-beta.5"}],"affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"41.10.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-j84w-jfhq-vhvj/GHSA-j84w-jfhq-vhvj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"42.0.0-alpha.1"},{"fixed":"42.9.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-j84w-jfhq-vhvj/GHSA-j84w-jfhq-vhvj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"43.0.0-alpha.1"},{"fixed":"43.4.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-j84w-jfhq-vhvj/GHSA-j84w-jfhq-vhvj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"44.0.0-alpha.1"},{"fixed":"44.0.0-beta.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-j84w-jfhq-vhvj/GHSA-j84w-jfhq-vhvj.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"}]}
