Description

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0, 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. This issue has been patched in versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0.

What Attestkeep does with this

Inside your cluster, without you opening a spreadsheet.

KnowsThe scanner refreshes its vulnerability database every six hours.
FindsEvery admitted image is rescanned every 24 hours by default (scan.rescanInterval). When Trivy rates this vulnerability critical for the image's package source, it appears in the image's findings by name. Findings without a fix are left out unless includeUnfixed is on.
Tells youA critical_finding event goes to the channels subscribed to it: e-mail, Slack, Teams, a webhook, Jira, GitLab or GitHub.
RefusesWith a policy that blocks critical findings, a pod with this image is refused at admission, a rollback to it included. Pods already running are not evicted.
RecordsEach decision is recorded with the policy that ran and its hash, then sealed under a signed checkpoint.
