Summary

The Crypto plugin for WordPress in versions up to and including 2.22 is vulnerable to information exposure. It registers an unauthenticated AJAX action (wp_ajax_nopriv_crypto_connect_ajax_process) that allows calling the register and savenft methods with only a publicly-available nonce check and no wallet signature verification. This enables unauthenticated attackers to set a site-wide global authentication state via a single transient, bypassing access controls for all visitors for one hour, plus inject arbitrary data into the plugin's custom_users table.

Risk Assessment

An attacker can completely bypass [crypto-block] shortcode restrictions and page-level access controls for all site visitors for one hour. Arbitrary data injection into the plugin's table is also possible, potentially leading to further abuse.

Recommendation

Update the Crypto plugin to a version newer than 2.22 as soon as it becomes available. Until then, consider disabling the plugin or restricting site access and monitor for unusual entries in the custom_users table.

Original NVD description (English source)

The Crypto plugin for WordPress is vulnerable to Information exposure 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 register and savenft methods with only a publicly-available nonce check and no wallet signature verification. This makes it possible for unauthenticated attackers to set a site-wide global authentication state via a single transient, bypassing all access controls for ALL visitors to the site. The impact is complete bypass of [crypto-block] shortcode restrictions and page-level access controls, affecting all site visitors for one hour, plus the ability to inject arbitrary data into the plugin's custom_users table.
