Electron: Sandboxed preload code cache can be poisoned by a compromised renderer
Quick fix
GHSA-qmv3-fv6v-rmhq — electron: upgrade to the fixed version with the command below.
npm install electron@42.10.0Details
### Impact
The cache Electron keeps for sandboxed preload scripts did not verify that a cached entry matched the preload it was served for. A compromised renderer could use this to run its own code in the preload context on a later load.
Apps are only affected if they load untrusted content. Apps that do not load untrusted content are not affected.
### Workarounds
There are no app side workarounds, you must update to a patched version of Electron.
### Fixed Versions
* `44.0.0-beta.6` * `43.5.0 ` * `42.10.0`
