Content shown in the app could use this to make a credentialed top-level request to another site that relies on SameSite cookies as a CSRF defence.\n\nApps are only affected if they load untrusted content and allow it to open new windows. Apps that deny new windows from untrusted content with `setWindowOpenHandler` are not affected.\n\n### Workarounds\n\nReturn `{ action: 'deny' }` from `setWindowOpenHandler` for windows opened by untrusted content.\n\n### Fixed Versions\n\n* `45.0.0-alpha.6`\n* `44.3.0`\n* `43.7.0`\n* `42.11.3`\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)","state":0,"publishedAt":"2026-10-22T16:47:54+00:00","modifiedAt":"2026-10-22T17:00:04.1780377+00:00","affected":[{"ecosystem":"npm","name":"electron","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"45.0.0-alpha.1"},{"kind":"fixed","version":"45.0.0-alpha.6"}]}],"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":"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":"0"},{"kind":"fixed","version":"42.11.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/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-2p8c-gr87-2676","https://nvd.nist.gov/vuln/detail/CVE-2026-113796","https://github.com/electron/electron/pull/53721","https://github.com/electron/electron/pull/53719","https://github.com/electron/electron/pull/53718","https://github.com/electron/electron/pull/53717","https://github.com/electron/electron/pull/53683","https://github.com/electron/electron/commit/a86ae4205ba2ba7ae60a6caa9d5d3a44321f2f9b","https://github.com/electron/electron/commit/98940cb274bb6adcb7cdb2da2d4495ac83119670","https://github.com/electron/electron/commit/652ef79ac79c6767b31e59b2f28d0d46114645e5","https://github.com/electron/electron/commit/0e6aca0618eeae50a18cfd50548b8688820629ed","https://github.com/electron/electron/commit/079b9b1594ee62c336adc3aa430d4c1cf62bd51e","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.6","https://github.com/electron/electron"],"sourceUrl":"https://github.com/advisories/GHSA-2p8c-gr87-2676","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-2p8c-gr87-2676","identifiers":["GHSA-2p8c-gr87-2676","CVE-2026-113796"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
