The 6Storage Rentals plugin for WordPress up to version 2.22.0 allows unauthenticated attackers to read and modify tenant profile data (including name, email, phone, address, and SSN) via the userId parameter in AJAX actions six_storage_get_user_info and six_storage_update_profile. No ownership, session, or nonce validation.

Recommendation

Immediately update the 6Storage Rentals plugin to the latest version. If no patch is available, temporarily disable the plugin.

Other vulnerabilities in 6Storage Rentals

CVE-2026-15303Critical
The 6Storage Rentals plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.27.0. The AJAX handler lacks verification, allowing unauthenticated attackers to log in as any existing user, including administrators.

Original NVD description (English source)

The 6Storage Rentals plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.22.0 via the `userId` parameter of the `six_storage_get_user_info` and `six_storage_update_profile` AJAX actions. This is due to the `six_storage_getUserInfo()` and `six_storage_updateProfile()` functions being registered on `wp_ajax_nopriv_*` hooks and accepting a tenant identifier directly from `$_POST['userId']` without performing any ownership verification, session binding, or nonce validation to confirm the requester has a legitimate relationship to the supplied ID. This makes it possible for unauthenticated attackers to read and modify arbitrary tenants' profile data — including name, email address, phone number, physical address, and SSN — by supplying an enumerated `userId` value in a crafted request to either handler.
