## 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.

Protocol::HTTP2 versions before 1.13 for Perl is vulnerable to a HTTP/2 Bomb.
Protocol::HTTP2's inbound HPACK path has no header-list size limit, so a small HTTP/2 request can expand into large server memory (the "HTTP/2 bomb").
The headers_decode method materialises a full key+value copy per indexed reference with no running size check, and the stream_header_block_add method appends (since version 1.12) every CONTINUATION frame to the per-stream buffer unbounded.
MAX_HEADER_LIST_SIZE (default 65536) is advertised in SETTINGS but never consulted on decode. It is absent from the decoder and from the :limits export tag.
