Prior to 39.8.6, 40.9.0, 41.1.1, and 42.0.0-beta.1, shell.openPath() did not reject paths containing embedded null bytes. Apps that perform string-only validation of file paths, for example checking the file extension, before passing them to shell.openPath() could be bypassed, allowing an attacker-controlled path to open a different file than the one that passed validation. Apps are only affected if they pass paths derived from untrusted input to shell.openPath() and rely on string-based validation without a filesystem check. This issue is fixed in versions 39.8.6, 40.9.0, 41.1.1, and 42.0.0-beta.1."}], "lastModified": "2026-10-08T13:54:00.020", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "1FC99B08-2972-4B17-A0E9-C8B36881780E", "versionEndExcluding": "39.8.6"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "56E4CE6E-6A00-4DF6-A720-141D67D4CA2D", "versionEndExcluding": "40.9.0", "versionStartIncluding": "40.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "B5945DA5-8081-4226-8699-AF3903D92F53", "versionEndExcluding": "41.1.1", "versionStartIncluding": "41.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "498062D8-5C83-4FC2-A04B-94F3228B2BED"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "A272F9F4-AB62-407C-B1A8-18586A474C19"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "BF49E260-9653-4D26-8B6C-C6FAFE697F5A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "2F3B609A-0CA5-4E8C-865E-CF79B6B0CCCC"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "308A710A-7965-40A0-87E4-2B66A8CEF87A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha6:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "6CFEB6F4-A38A-43BC-92B1-2E1DC8BBD1D7"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "7B9FD9F4-48E0-4EA2-957D-57ADA2A3D42A"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
