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.","evidence":"cve:CVE-2026-102677","products":[{"name":{"value":"electron","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-102677","aliases":["CVE-2026-102677"],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":7.8,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"electron","product":"electron","versions":[{"status":"affected","version":">= 42.3.3, < 42.10.0"},{"status":"affected","version":">= 43.0.0-beta.1, < 43.5.0"},{"status":"affected","version":">= 44.0.0-alpha.1, < 44.0.0-beta.6"}]}],"modified":"2026-10-02T12:18:18.477Z","provider":"cve","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"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102677","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-02T12:18:07.959498Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-02T12:18:18.477Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-29T17:43:26.960Z"}}},"related_cves":[{"value":"CVE-2026-102677","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":7895,"next_before":7895}
