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."}], "lastModified": "2026-10-08T20:24:30.737", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "0983EAA7-6B7F-4F8A-83DE-0F3769CC6C4A", "versionEndIncluding": "42.10.0", "versionStartIncluding": "42.3.3"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "9079739C-BB0A-4D28-8AD4-F4558D6773B2", "versionEndExcluding": "43.4.2", "versionStartIncluding": "43.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "94D88EA0-06B8-4682-B01F-D3E1D7F6F806"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "796732E1-53E5-4D7F-AA0C-9CBDD29F7210"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "522046B0-9E6A-481A-A8B2-69AD79D61259"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "7073A25C-D7C8-42C6-9A19-AF45BE0CDF9F"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "FD3928C5-4200-4CA6-864C-2537CFCF1039"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha6:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "F2E8594F-E690-47D9-BFB9-22E127F4EEC8"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha7:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "3106D6D5-37B3-4422-AB92-95E81B8B18F3"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha8:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "990B95FF-4B70-4E2A-9ADE-96DB4FD83F58"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:alpha9:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "550B3853-4CD1-491C-9C66-E3DBDEF5415F"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:beta1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "F3DCC540-D8FC-4602-8150-4F5FA7E6AE8F"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:beta2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "A6DBFDE8-90FE-47A1-9311-CDADB8598818"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:beta3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "42385506-40E0-4520-86B8-7EA679DD68F5"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:beta4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "2061B84C-AC6C-4F81-B14B-EA747246A048"}, {"criteria": "cpe:2.3:a:electronjs:electron:44.0.0:beta5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "48A97AF4-2C03-425F-ABB4-50D522C1426D"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
