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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD 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":null}],"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://euvd.enisa.europa.eu/vulnerability/EUVD-2026-89179","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 29, 2026, 5:43:26 PM","dateUpdated":"Oct 2, 2026, 12:18:18 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
