The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Start learningUpgrade electron
to version 23.2.3, 25.0.0-alpha.2 or higher.
electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.
Affected versions of this package are vulnerable to Improper Access Control via nested unserializable return value when using contextIsolation
and contextBridge
are affected.
Exploiting this vulnerability allows code running in the main world context in the renderer to reach into the isolated Electron context and perform privileged actions.
Note
This issue is exploitable under either of two conditions:
If an API exposed to the main world via contextBridge
can return an object or array that contains a JS object that cannot be serialized, such as a canvas rendering context. This would normally result in an Error: object could not be cloned
exception being thrown.
If an API exposed to the main world via contextBridge
has a return value that throws a user-generated exception while being sent over the bridge, such as a dynamic getter property on an object that throws an error when being computed.
The app-side workaround is to ensure that such a case, as mentioned in the workaround section, is not possible.
Ensure all values returned from a function exposed over the context bridge are supported and that any objects returned from functions do not have dynamic getters that can throw exceptions.
Auditing your exposed API is likely to be quite difficult, so we strongly recommend you update to a patched version of Electron.
