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.643.5.042.10.0
