{"id":"CVE-2026-113796","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-113796","generatedAt":"2026-10-28T03:42:11.116Z","title":"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.","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.","published":"2026-10-21T17:18:25.000Z","lastModified":"2026-10-23T15:17:25.000Z","status":"Undergoing Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N"},"cwe":["CWE-352"],"affected":[],"epss":{"score":0.00219,"percentile":0.12272,"date":"2026-10-27","history":[{"date":"2026-10-22","score":0.00184,"percentile":0.07535}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.22%).
