From 42.3.3 until 42.10.0, 43.5.0, and 44.0.0-beta.6, Electron's sandboxed preload code cache did not verify that a cached entry matched the preload it was served for. A compromised renderer could write attacker-controlled cache data and cause Electron to reuse it for a later load, executing the renderer's code in the more privileged preload context. The issue affects applications that load untrusted content. This issue is fixed in versions 42.10.0, 43.5.0, and 44.0.0-beta.6.","state":0,"publishedAt":"2026-09-29T17:43:26.96+00:00","modifiedAt":"2026-10-02T12:18:18.477+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 42.3.3, < 42.10.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 43.0.0-beta.1, < 43.5.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 44.0.0-alpha.1, < 44.0.0-beta.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-qmv3-fv6v-rmhq","https://github.com/electron/electron/pull/52480","https://github.com/electron/electron/commit/000453e399bd1dee5e86376cdd9ece5fc071e601","https://github.com/electron/electron/commit/25ba8be57c65a83d8c14ebb8aa37693df17a04f3","https://github.com/electron/electron/commit/c38d6fd68756f04647ea857bdb6a2abec332e217","https://github.com/electron/electron/releases/tag/v42.10.0","https://github.com/electron/electron/releases/tag/v43.5.0","https://github.com/electron/electron/releases/tag/v44.0.0-beta.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102677","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102677","identifiers":["CVE-2026-102677"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
