What the vulnerability does
01Description
The Crypto plugin for WordPress is vulnerable to unauthorized manipulation of data in all versions up to, and including, 2.22. This is due to the plugin registering an unauthenticated AJAX action (wp_ajax_nopriv_crypto_connect_ajax_process) that allows calling the crypto_delete_json method with only a publicly-available nonce check. This makes it possible for unauthenticated attackers to delete specific JSON files matching the pattern *_pending.json within the wp-content/uploads/yak/ directory, causing data loss and denial of service for plugin workflows that rely on these artifacts.
Explanation of Vulnerability in Simple Terms
02Summary
Crypto Tool versions 2.22 and earlier lack proper authorization checks, allowing unauthenticated attackers to modify data via network requests. No authentication or user interaction is required. The vulnerability affects data integrity but not confidentiality or availability. Update to a version newer than 2.22.
