Impact
Apps that pass VideoFrame objects (from the WebCodecs API) across the contextBridge are vulnerable to a context isolation bypass. An attacker who can execute JavaScript in the main world (for example, via XSS) can use a bridged VideoFrame to gain access to the isolated world, including any Node.js APIs exposed to the preload script.
Apps are only affected if a preload script returns, resolves, or passes a VideoFrame object to the main world via contextBridge.exposeInMainWorld(). Apps that do not bridge VideoFrame objects are not affected.
Workarounds
Do not pass VideoFrame objects across contextBridge. If an app needs to transfer video frame data, serialize it to an ArrayBuffer or ImageBitmap before bridging.
Fixed Versions
41.0.0-beta.840.7.039.8.0
