{"id":"CVE-2026-113796","state":"PUBLISHED","title":"Electron: SameSite cookie restrictions are not applied to windows opened from links","description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6, Electron treated pages opened into a new window from links as application-initiated navigations instead of preserving the page containing the link as the initiator. The resulting top-level request could be classified as same-site, causing SameSite=Strict cookies to be sent and Sec-Fetch-Site not to identify the initiating page. An application that loads untrusted content and permits it to open new windows could therefore allow that content to make a credentialed request to another site that relies on SameSite cookies for CSRF protection. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6.","publishedAt":"2026-10-21T16:04:42.688Z","updatedAt":"2026-10-23T15:12:14.165Z","severity":{"score":4.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["electron electron"],"affected":[{"vendor":"electron","product":"electron","versions":[{"version":"< 42.11.3","status":"affected"},{"version":">= 43.0.0-alpha.1, < 43.7.0","status":"affected"},{"version":">= 44.0.0-alpha.1, < 44.3.0","status":"affected"},{"version":">= 45.0.0-alpha.1, < 45.0.0-alpha.6","status":"affected"}]}],"references":["https://github.com/electron/electron/security/advisories/GHSA-2p8c-gr87-2676","https://github.com/electron/electron/pull/53683","https://github.com/electron/electron/pull/53717","https://github.com/electron/electron/pull/53718","https://github.com/electron/electron/pull/53719","https://github.com/electron/electron/pull/53721","https://github.com/electron/electron/commit/079b9b1594ee62c336adc3aa430d4c1cf62bd51e","https://github.com/electron/electron/commit/0e6aca0618eeae50a18cfd50548b8688820629ed","https://github.com/electron/electron/commit/652ef79ac79c6767b31e59b2f28d0d46114645e5","https://github.com/electron/electron/commit/98940cb274bb6adcb7cdb2da2d4495ac83119670","https://github.com/electron/electron/commit/a86ae4205ba2ba7ae60a6caa9d5d3a44321f2f9b","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"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:10:43.281Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/113xxx/CVE-2026-113796.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-113796","state":"PUBLISHED","datePublished":"2026-10-21T16:04:42.688Z","dateUpdated":"2026-10-23T15:12:14.165Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-20T17:39:41.373Z"},"containers":{"cna":{"title":"Electron: SameSite cookie restrictions are not applied to windows opened from links","descriptions":[{"lang":"en","value":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS.
