| Título | jeremyckahn Chitchatter develop branch @ 23b62a8 (source) authentication bypass / identity takeover |
|---|
| Descripción | isConfigMessageEvent derives the trusted parent origin from the attacker-controllable parentDomain URL parameter; a malicious embedder can deliver a config postMessage with attacker-generated ECDSA key material that are merged into UserSettings and persisted in IndexedDB, enabling impersonation in E2E rooms. Static source review verified the full chain. |
