CVE-2026-47430
## Summary The iOS implementation of `cordova-plugin-inappbrowser` passes the `id` field from a `WKScriptMessage` body to `commandDelegate sendPluginResult:callbackId:` with no format validation (`CDVWKInAppBrowser.m:560–574`). Any web content loaded inside the InAppBrowser can fire any pending Cordova callback in the host app by posting a message whose `id` field is a guessable or enumerated callback identifier. An attack abusing this weakness must be tailored to the specific plugins and callback IDs the host app uses. Though an attacker with knowledge of common Cordova plugin configurations could craft reusable payloads targeting widely-adopted plugins. ## Impact An unauthenticated remote attacker who controls content displayed in the InAppBrowser — via a URL the app opens (OAuth redirect, marketing link, deep-link target) or a network interception — can call `window.webkit.messageHandlers.cordova_iab.postMessage({id: '<victim-callback-id>', d: '...'})` to fire callbacks belonging to any other installed Cordova plugin (Camera, Contacts, File, Geolocation). Cordova callback IDs follow the predictable format `<PluginName><sequential-integer>`, making enumeration feasible. Successfu
