CVE-2026-47430— Apache Cordova Plugin InAppBrowser 输入验证错误漏洞

Cordova Plugin InAppBrowser: iOS: Arbitrary Cordova callback IDs can be dispatched without validation from InAppBrowser WebViews

## 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. Successful exploitation allows the attacker to spoof plugin results across trust boundaries — for example, injecting a forged camera approval, a fabricated contacts list, or a crafted file-read response. This issue affects Cordova Plugin InAppBrowser: from 3.1.0 through 6.0.0. Users are recommended to upgrade to version 6.0.1, which fixes the issue.

输入验证不恰当

Apache Cordova Plugin InAppBrowser 输入验证错误漏洞

Apache Cordova Plugin InAppBrowser是美国阿帕奇（Apache）基金会的一个嵌入式浏览器插件。 Apache Cordova Plugin InAppBrowser 3.1.0版本至6.0.0版本存在输入验证错误漏洞，该漏洞源于iOS实现中未对WKScriptMessage消息体的id字段进行格式验证，可能导致远程攻击者伪造插件结果并跨信任边界进行攻击。
