Advisory

Source description from Wordfence Intelligence, credited to Dimopoulos Elias.

An issue was discovered in the Popup Maker plugin before 1.8.13 for WordPress. An unauthenticated attacker can partially control the arguments of the do_action function to invoke certain popmake_ or pum_ methods, as demonstrated by controlling content and delivery of popmake-system-info.txt (aka the "support debug text file").
