Description
Impact
The nodeIntegrationInWorker webPreference was not correctly scoped in all configurations. In certain process-sharing scenarios, workers spawned in frames configured with nodeIntegrationInWorker: false could still receive Node.js integration.
Apps are only affected if they enable nodeIntegrationInWorker. Apps that do not use nodeIntegrationInWorker are not affected.
Workarounds
Avoid enabling nodeIntegrationInWorker in apps that also open child windows or embed content with differing webPreferences.
