{"id":"GHSA-2p8c-gr87-2676","summary":"Electron: SameSite cookie restrictions are not applied to windows opened from links","details":"### Impact\n\nPages opened into a new window from a link were loaded as if the app itself had navigated there rather than the page that contained the link, so the request was treated as same-site: `SameSite=Strict` cookies were sent and `Sec-Fetch-Site` did not identify the initiating page. 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)","aliases":["CVE-2026-113796"],"modified":"2026-10-22T17:00:04.178037719Z","published":"2026-10-22T16:47:54Z","database_specific":{"cwe_ids":["CWE-352"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-10-22T16:47:54Z","nvd_published_at":"2026-10-21T17:18:24Z"},"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-2p8c-gr87-2676"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113796"},{"type":"WEB","url":"https://github.com/electron/electron/pull/53721"},{"type":"WEB","url":"https://github.com/electron/electron/pull/53719"},{"type":"WEB","url":"https://github.com/electron/electron/pull/53718"},{"type":"WEB","url":"https://github.com/electron/electron/pull/53717"},{"type":"WEB","url":"https://github.com/electron/electron/pull/53683"},{"type":"WEB","url":"https://github.com/electron/electron/commit/a86ae4205ba2ba7ae60a6caa9d5d3a44321f2f9b"},{"type":"WEB","url":"https://github.com/electron/electron/commit/98940cb274bb6adcb7cdb2da2d4495ac83119670"},{"type":"WEB","url":"https://github.com/electron/electron/commit/652ef79ac79c6767b31e59b2f28d0d46114645e5"},{"type":"WEB","url":"https://github.com/electron/electron/commit/0e6aca0618eeae50a18cfd50548b8688820629ed"},{"type":"WEB","url":"https://github.com/electron/electron/commit/079b9b1594ee62c336adc3aa430d4c1cf62bd51e"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v42.11.3"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v43.7.0"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v44.3.0"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v45.0.0-alpha.6"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"45.0.0-alpha.1"},{"fixed":"45.0.0-alpha.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2p8c-gr87-2676/GHSA-2p8c-gr87-2676.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"44.0.0-alpha.1"},{"fixed":"44.3.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2p8c-gr87-2676/GHSA-2p8c-gr87-2676.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"43.0.0-alpha.1"},{"fixed":"43.7.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2p8c-gr87-2676/GHSA-2p8c-gr87-2676.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"42.11.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2p8c-gr87-2676/GHSA-2p8c-gr87-2676.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N"}]}
