Description
WPPConnect Server through 2.10.74 contains a missing authentication vulnerability that allows unauthenticated attackers to send WhatsApp messages by calling the Chatwoot webhook route without verifyToken middleware. Attackers who know or guess a connected session name can POST outgoing message bodies to send arbitrary texts or files from that account to any number.
