Overview
Affected versions of this package are vulnerable to Origin Validation Error in contextBridge. An attacker can gain access to the isolated preload world and its capabilities by hijacking Function.prototype.bind when Promise-returning functions are exposed to untrusted web content. This may escalate to Node.js access if the renderer is unsandboxed or nodeIntegration is enabled.
Note: This is only exploitable if Promise-returning functions are exposed via contextBridge in windows that load untrusted content.
