Description
Chatwoot before 4.17.0 contains an authorization bypass vulnerability that allows authenticated agent bots to access other accounts by supplying a foreign contact inbox source_id. Attackers can call the conversations create endpoint with another account's source_id to create or retrieve conversations and post messages to that account's contacts.
