Subscriber-level post deletion via unchecked AJAX request
Published Jan 24, 2022 · Updated Aug 3, 2024
Missing authorization in Themeum Qubely before 1.7.8 allows remote authenticated users to delete arbitrary WordPress posts. The qubely_delete_saved_block AJAX handler neither checks user capability nor verifies that the requested post belongs to Qubely before deleting it. Subscriber-level access is sufficient, and exploitation removes attacker-selected site content without another user's interaction.
