Prior to 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, apps that call clipboard.readImage() may be vulnerable to a denial of service. If the system clipboard contains image data that fails to decode, the resulting null bitmap is passed unchecked to image construction, triggering a controlled abort and crashing the process. Apps are only affected if they call clipboard.readImage(). Apps that do not read images from the clipboard are not affected. This issue does not allow memory corruption or code execution. This vulnerability is fixed in 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","score":3.3},"cwes":["CWE-476"],"references":["https://github.com/electron/electron/security/advisories/GHSA-f37v-82c4-4x64"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-34781","score":0.00144,"percentile":0.03673,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f37v-82c4-4x64","url":"https://osv.dev/vulnerability/GHSA-f37v-82c4-4x64","summary":"Electron: Crash in clipboard.readImage() on malformed clipboard image data","modified":"2026-04-08T12:08:25.778807Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<39.8.5"],"fixed":["39.8.5"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=40.0.0-alpha.1 <40.8.5"],"fixed":["40.8.5"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=41.0.0-alpha.1 <41.1.0"],"fixed":["41.1.0"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=42.0.0-alpha.1 <42.0.0-alpha.5"],"fixed":["42.0.0-alpha.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
