{"id":"CVE-2026-115570","aliases":["GHSA-jr5w-w6x2-84p9"],"url":"https://o3.security/vulnerability/CVE-2026-115570","summary":"Electron: Mitigation for compromised eMudhra intermediate certificates","details":"### Impact\n\nA set of eMudhra intermediate certificates were compromised and are being blocked by browsers and other TLS clients. This Electron update adds the same block to both Chromium networking and Node.js `tls`, `https` and `fetch`. On earlier versions, an attacker holding a certificate issued through these intermediates and able to intercept network traffic could impersonate a TLS server to an app.\n\nApps are only affected if they make TLS connections over a network an attacker can intercept. Apps that make no network connections are not affected.\n\nOther software has shipped the same mitigation, including Go (CVE-2026-111943) and Firefox (CVE-2026-113470).\n\n### Workarounds\n\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n\n* `45.0.0-beta.6`\n* `44.9.1`\n* `43.8.1`\n* `42.11.16`\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)","published":"2026-10-23T18:13:53.961Z","modified":"2026-10-25T02:45:39.923704031Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"45.0.0-beta.6"},{"ecosystem":"npm","name":"electron","fixedVersion":"44.9.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"43.8.1"},{"ecosystem":"npm","name":"electron","fixedVersion":"42.11.16"}],"fix":{"url":"https://github.com/electron/electron/commit/093583c71be71c85453e6e225137bf2af755fbcc","label":"electron/electron@093583c"},"references":[{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v42.11.16"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v43.8.1"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v44.9.1"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v45.0.0-beta.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115570.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-jr5w-w6x2-84p9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115570"},{"type":"FIX","url":"https://github.com/electron/electron/commit/093583c71be71c85453e6e225137bf2af755fbcc"},{"type":"FIX","url":"https://github.com/electron/electron/commit/1d2f13b1985444a38abf389db38228ac42f5bcad"},{"type":"FIX","url":"https://github.com/electron/electron/commit/817c43f925677eb88034bfba4f0b8dfd28e7ad20"},{"type":"FIX","url":"https://github.com/electron/electron/commit/e02265be96c5e13ae43644ef482b718e1e800499"},{"type":"FIX","url":"https://github.com/electron/electron/pull/55127"},{"type":"FIX","url":"https://github.com/electron/electron/pull/55128"},{"type":"FIX","url":"https://github.com/electron/electron/pull/55129"},{"type":"FIX","url":"https://github.com/electron/electron/pull/55130"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-25T02:45:39.923704031Z"}}
