{"schema":"threatline.record/2","record":{"id":"CVE-2026-113796","aliases":["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
