An origin-based handler could therefore let untrusted content launch an OS-registered external application.\n\nApps are only affected if they grant `openExternal` based on the requesting origin and let untrusted content open or navigate windows. Apps whose permission handler denies `openExternal` for untrusted content are not affected.\n\n### Workarounds\nDeny the `openExternal` permission for untrusted content, or deny the windows it opens with `setWindowOpenHandler`.\n\n### Fixed Versions\n* `45.0.0-alpha.5`\n* `44.3.0`\n* `43.7.0`\n* `42.11.3`\n\n### For more information\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)","state":0,"publishedAt":"2026-10-22T16:43:59+00:00","modifiedAt":"2026-10-22T17:00:05.1737701+00:00","affected":[{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"42.11.3"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"43.0.0-alpha.1"},{"kind":"fixed","version":"43.7.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"44.0.0-alpha.1"},{"kind":"fixed","version":"44.3.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"45.0.0-alpha.1"},{"kind":"fixed","version":"45.0.0-alpha.5"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-997q-gvvc-jwmx","https://nvd.nist.gov/vuln/detail/CVE-2026-114121","https://github.com/electron/electron/pull/53699","https://github.com/electron/electron/pull/53698","https://github.com/electron/electron/pull/53697","https://github.com/electron/electron/pull/53696","https://github.com/electron/electron/pull/53682","https://github.com/electron/electron/commit/e3a400911084537bce7380ffea8af939572ce8dd","https://github.com/electron/electron/commit/e0a20d5277b567aea8603f8e9852a4341407a586","https://github.com/electron/electron/commit/92a783952891805f2f82f344c40a6917b98a7d98","https://github.com/electron/electron/commit/8aa5414f73792ed3b2e3f9ab6391b1832e6dc2c3","https://github.com/electron/electron/commit/25057643bf6d9a20bad69e45707551ccf546f5ce","https://github.com/electron/electron/releases/tag/v42.11.3","https://github.com/electron/electron/releases/tag/v43.7.0","https://github.com/electron/electron/releases/tag/v44.3.0","https://github.com/electron/electron/releases/tag/v45.0.0-alpha.5","https://github.com/electron/electron"],"sourceUrl":"https://github.com/advisories/GHSA-997q-gvvc-jwmx","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-997q-gvvc-jwmx","identifiers":["GHSA-997q-gvvc-jwmx","CVE-2026-114121"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
