NVD description
Baileys is a cocket-based TS/JavaScript API for WhatsApp Web. In versions prior to both 6.7.22 and 7.0.0-rc12, any Baileys session can be sent a malicious payload via the placeholderResendMessage and trigger a fake messages.upsert event with a fake message key and payload. This allows anyone to spoof messages. The same exploit also allows an attacker to corrupt the app state sync system by sending fake key shares, and also allows for history sync spoofing which also serves the same problem, injecting fake previous context or "on-demand" sync. This issue has been fixed in versions 6.7.22 and 7.0.0-rc12.

Post summary
An announcement of CVE‑2026‑48063 reveals a vulnerability in Baileys API that permits malicious payloads in certain versions, but no exploit code, active attacks, or patch information are provided.
🚨Critical - Baileys Message Spoofing & App State Corruption (CVE-2026-48063) An authentication-bypass-by-spoofing flaw in Baileys, the popular open-source WhatsApp Web API library, lets a remote unauthenticated attacker send a maliciously crafted protocolMessage payload through placeholderResendMessage. This triggers a fake messages.upsert event carrying an attacker-controlled message key and payload — meaning anyone can spoof arbitrary inbound messages on a target session. The same vector also corrupts the app state sync system via forged key shares and enables history-sync spoofing, letting an attacker inject fake prior conversation context or bogus on-demand sync data. No credentials and no user interaction required. 👉Upgrade to Baileys 6.7.22 or 7.0.0-rc12.
