The Devs Accounting – Simple Accounting and Invoicing Solution plugin for WordPress is vulnerable to unauthorized modification/deletion of data due to a missing capability check on the delete_single_account() function in versions up to, and including, 1.2.0. The REST route 'devs-accounting/v1/delete-account/(?P<id>\d+)' is registered without any permission_callback, which causes WordPress to expose the endpoint to public, unauthenticated access. This makes it possible for unauthenticated attackers to soft-delete arbitrary accounting account records (wp_dac_accounts) by issuing a simple GET request to the endpoint with any account ID.

The Devs Accounting – Simple Accounting and Invoicing Solution plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.2.0. This is due to the get_single_account() REST API callback being registered with a permission_callback that unconditionally returns true, providing no authentication or authorization checks on the /devs-accounting/v1/get-account/<id> endpoint. This makes it possible for unauthenticated attackers to read arbitrary private financial account records (including account name, bank name, and opening balance) by enumerating the numeric account ID, resulting in sensitive information disclosure.
