new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

contextbridge/security

3 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

contextBridge ipcRenderer exposure restriction

Attempting to send the entire ipcRenderer module as an object over the contextBridge will result in an empty object on the receiving side. Sending ipcRenderer in full is a security footgun as it allows any code to send any message. Instead, provide a safe wrapper that exposes only specific ipcRenderer methods.

contextBridge ipcRenderer breaking change

As of a change in Electron (PR #40330), ipcRenderer can no longer be sent over the contextBridge.

contextBridge safe ipcRenderer wrapper example

Example of providing a safe wrapper for ipcRenderer instead of exposing the entire module: // Preload (Isolated World) contextBridge.exposeInMainWorld('electron', { onMyEventName: (callback) => ipcRenderer.on('MyEventName', (e, ...args) => callback(args)) }) // Renderer (Main World) window.electron.onMyEventName(data => { /* ... */ })
