Description Andrej Nemec 2016-08-22 13:58:50 UTC

A path traversal vulnerability was found in the Core Ajax handlers of
the WordPress Admin API. This issue can (potentially) be used by an
authenticated user (Subscriber) to create a denial of service condition
of an affected WordPress site.

It is also possible to trigger this issue via Cross-Site Request Forgery
as the nonce check is done too late in this case.
