Photo Reviews for WooCommerce < 1.2.31 - Missing Authorization to Unauthenticated Arbitrary Post Deletion via 'wcpr_image_upload_id' Parameter

Description

The Photo Reviews for WooCommerce plugin for WordPress is vulnerable to Arbitrary Content Deletion in versions up to, and including, 1.2.30. This is due to the plugin storing attacker-controlled post IDs from the wcpr_image_upload_id parameter of a public review submission into the review's reviews-images comment meta without verifying that the IDs correspond to attachments owned by the submitter, combined with the delete_reviews_image() handler unconditionally calling wp_delete_post( $id, true ) on every stored ID when the review is deleted. This makes it possible for unauthenticated attackers to permanently delete arbitrary posts, pages, products, or media attachments on the site whenever an administrator subsequently deletes the attacker's review (or when WordPress's built-in wp_scheduled_delete cron empties the comment trash after 30 days).
