Technical details

The 6Storage Rentals plugin for WordPress (up to version 2.22.0) is vulnerable to an Insecure Direct Object Reference (IDOR) / Authorization Bypass via the 'userId' parameter. The functions 'six_storage_getUserInfo()' and 'six_storage_updateProfile()' are registered via 'wp_ajax_nopriv_*' hooks, making them accessible to unauthenticated users. Because the plugin fails to implement ownership verification, session binding, or nonce validation, an attacker can supply arbitrary user IDs in AJAX requests to the 'six_storage_get_user_info' and 'six_storage_update_profile' actions. This allows for the unauthorized retrieval and modification of tenant PII, including names, emails, phone numbers, addresses, and Social Security Numbers (SSN).
