{"id":"CVE-2026-102675","aliases":["GHSA-j84w-jfhq-vhvj"],"url":"https://o3.security/vulnerability/CVE-2026-102675","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)","published":"2026-09-29T16:54:29.218Z","modified":"2026-10-21T09:31:59.110673395Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"41.10.6"},{"ecosystem":"npm","name":"electron","fixedVersion":"42.9.2"},{"ecosystem":"npm","name":"electron","fixedVersion":"43.4.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"44.0.0-beta.5"}],"fix":{"url":"https://github.com/electron/electron/commit/4d2784cc8592471ee2276235b8c2a03efddf937d","label":"electron/electron@4d2784c"},"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102675.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-j84w-jfhq-vhvj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102675"},{"type":"FIX","url":"https://github.com/electron/electron/commit/4d2784cc8592471ee2276235b8c2a03efddf937d"},{"type":"FIX","url":"https://github.com/electron/electron/commit/80178e4631cb2f6a5e42f8e793b2ae9624e78a0d"},{"type":"FIX","url":"https://github.com/electron/electron/commit/c595b05976e7a885465b043d17e00a92fc3c3397"},{"type":"FIX","url":"https://github.com/electron/electron/commit/ef75c4b98caaa3ebc615f1eba302027028ee04d2"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T09:31:59.110673395Z"}}
