CVE-2021-24809
The BP Better Messages WordPress plugin before 1.9.9.41 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,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
