Description

The Kadence Blocks – Gutenberg Blocks for Page Builder Features plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.7.7. This is due to a mismatch between the object used for authorization and the object actually accessed in the Optimize_Rest_Controller's create_item(), get_item(), delete_item(), and bulk_delete_items() endpoints β€” authorization is checked via current_user_can('edit_post'/'delete_post', $post_id) against the user-supplied post_id, while the storage layer keys analysis records on sha256($post_path) from a separately supplied, attacker-controlled post_path parameter, with no enforcement that post_path corresponds to post_id. This makes it possible for authenticated attackers, with Contributor-level access and above, to read or delete optimizer analysis records belonging to posts owned by other users by submitting their own post_id (which passes the capability check) together with the victim post's path.

Executive Summary

The vulnerability in the Kadence Blocks plugin for WordPress is an Insecure Direct Object Reference (IDOR) issue. It occurs because the plugin checks user authorization against a post ID supplied by the user, but accesses data based on a different parameter, the post path, which is attacker-controlled. This mismatch allows an authenticated user with Contributor-level access or higher to read or delete optimizer analysis records belonging to posts owned by other users by submitting their own post ID (which passes the authorization check) along with the victim's post path.

Impact Analysis

This vulnerability can allow an attacker with Contributor-level access or higher to read or delete optimizer analysis records of posts owned by other users. This means unauthorized access to or deletion of data related to other users' posts, potentially leading to data loss or exposure of sensitive information within the WordPress site.
