A vulnerability in versions prior to 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 allows attackers who have control over a given apps update server / update storage to serve maliciously crafted update packages that pass the code signing validation check…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Electron is a framework for writing cross-platform desktop applications using JavaScript (JS), HTML, and CSS. A vulnerability in versions prior to 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 allows attackers who have control over a given apps update server / update storage to serve maliciously crafted update packages that pass the code signing validation check but contain malicious code in some components. This kind of attack would require significant privileges in a potential victim's own auto updating infrastructure and the ease of that attack entirely depends on the potential victim's infrastructure security. Electron versions 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 contain a fix for this issue. There are no known workarounds.
