CVE-2026-48063 (opens in a new tab)How to fix?
Upgrade baileys to version 6.7.22, 7.0.0-rc12 or higher.
Overview
baileys is an A WebSockets library for interacting with WhatsApp Web
Affected versions of this package are vulnerable to Origin Validation Error via the messages.upsert event handling process. An attacker can inject forged messages, spoof message history, and corrupt application state by sending maliciously crafted protocolMessage payloads. This can be achieved by exploiting the handling of placeholderResendMessage and fake key shares, allowing unauthorized manipulation of message events and history synchronization.
Workaround
This vulnerability can be mitigated by dropping messages.upsert events that contain a requestId field and turning off automatic history sync by setting shouldSyncHistoryMessage: () => false in the socket configuration. There are no workarounds for the app state sync jamming.
