提出 #1015027: jeremyckahn Chitchatter develop branch @ 23b62a8 (source) authentication bypass / identity takeover情報

タイトルjeremyckahn Chitchatter develop branch @ 23b62a8 (source) authentication bypass / identity takeover
説明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.
