{"id":"CVE-2022-36077","aliases":["GHSA-p2jh-44qj-pf2v"],"url":"https://o3.security/vulnerability/CVE-2022-36077","summary":"Electron subject to Exfiltration of hashed SMB credentials on Windows via file:// redirect","details":"The Electron framework enables writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 21.0.0-beta.1, 20.0.1, 19.0.11, and 18.3.7, Electron is vulnerable to Exposure of Sensitive Information. When following a redirect, Electron delays a check for redirecting to file:// URLs from other schemes. The contents of the file is not available to the renderer following the redirect, but if the redirect target is a SMB URL such as `file://some.website.com/`, then in some cases, Windows will connect to that server and attempt NTLM authentication, which can include sending hashed credentials.This issue has been patched in versions: 21.0.0-beta.1, 20.0.1, 19.0.11, and 18.3.7. Users are recommended to upgrade to the latest stable version of Electron. If upgrading isn't possible, this issue can be addressed without upgrading by preventing redirects to file:// URLs in the `WebContents.on('will-redirect')` event, for all WebContents as a workaround.","published":"2022-11-08T00:00:00Z","modified":"2026-08-08T03:47:33.006437321Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"18.3.7"},{"ecosystem":"npm","name":"electron","fixedVersion":"20.0.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"19.0.11"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36077.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-p2jh-44qj-pf2v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36077"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:47:33.006437321Z"}}
