Sucuri Security WordPress plugin through version 2.7.3 contains a path traversal vulnerability in the pageIntegritySubmission() method in src/integrity.lib.php that allows authenticated administrators to delete arbitrary files by supplying directory traversal sequences in the sucuriscan_integrity parameter.
