Electron: nodeIntegrationInWorker not correctly scoped in shared renderer processes

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...

GHSA-532V-XPQ5-8H95 Electron: Use-after-free in offscreen child window paint callback

Impact Apps that use offscreen rendering and allow child windows via window.open may be vulnerable to a use-after-free. If the parent offscreen WebContents is destroyed while a child window remains open, subsequent paint frames on the child dereference freed memory, which may lead to a crash or...

GHSA-MWMH-MQ4G-G6GR Electron: Registry key path injection in app.setAsDefaultProtocolClient on Windows

Impact On Windows, app.setAsDefaultProtocolClientprotocol did not validate the protocol name before writing to the registry. Apps that pass untrusted input as the protocol name may allow an attacker to write to arbitrary subkeys under HKCU\Software\Classes, potentially hijacking existing protocol...

GHSA-9W97-2464-8783 Electron: Use-after-free in download save dialog callback

Impact Apps that allow downloads and programmatically destroy sessions may be vulnerable to a use-after-free. If a session is torn down while a native save-file dialog is open for a download, dismissing the dialog dereferences freed memory, which may lead to a crash or memory corruption. Apps tha...

GHSA-8337-3P73-46F4 Electron: Use-after-free in WebContents fullscreen, pointer-lock, and keyboard-lock permission callbacks

Impact Apps that register an asynchronous session.setPermissionRequestHandler may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invokin...

GHSA-JJP3-MQ3X-295M Electron: Use-after-free in PowerMonitor on Windows and macOS

Impact Apps that use the powerMonitor module may be vulnerable to a use-after-free. After the native PowerMonitor object is garbage-collected, the associated OS-level resources a message window on Windows, a shutdown handler on macOS retain dangling references. A subsequent session-change event...

GHSA-9WFR-W7MM-PC7F Electron: Renderer command-line switch injection via undocumented commandLineSwitches webPreference

Impact An undocumented commandLineSwitches webPreference allowed arbitrary switches to be appended to the renderer process command line. Apps that construct webPreferences by spreading untrusted configuration objects may inadvertently allow an attacker to inject switches that disable renderer...

Electron: Unquoted executable path in app.setLoginItemSettings on Windows

Impact On Windows, app.setLoginItemSettingsopenAtLogin: true wrote the executable path to the Run registry key without quoting. If the app is installed to a path containing spaces, an attacker with write access to an ancestor directory may be able to cause a different executable to run at login...

Electron: HTTP Response Header Injection in custom protocol handlers and webRequest

Impact Apps that register custom protocol handlers via protocol.handle / protocol.registerSchemesAsPrivileged or modify response headers via webRequest.onHeadersReceived may be vulnerable to HTTP response header injection if attacker-controlled input is reflected into a response header name or...

GHSA-9899-M83M-QHPJ Electron: USB device selection not validated against filtered device list

Impact The select-usb-device event callback did not validate the chosen device ID against the filtered list that was presented to the handler. An app whose handler could be influenced to select a device ID outside the filtered set would grant access to a device that did not match the renderer's...
