CVE-2026-34781: Electronjs Electron

Low severity, CVSS 3.3. EPSS: 0.1% chance of exploitation in the next 30 days.

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. 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.

Affected products

• Electronjs Electron: up to and including 39.8.4; from 40.0.0, up to and including 40.8.4; from 41.0.0, before 41.1.0 (fixed in 41.1.0); version 41.2.0 only; version 42.0.0 only
