Summary

Trudesk through 1.2.11 contains an authorization bypass in apiMessages.send that lets authenticated users post messages as other users. The fix for CVE-2022-1931 is incomplete, and attackers can supply arbitrary owner and cId values to POST /api/v1/messages/send to inject spoofed messages into conversations they do not belong to. CWE-639 covers this flaw. An attacker needs a low-privileged account on the system.
