6Storage Rentals vulnerabilities

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.

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.

Server-Side Request Forgery (SSRF) vulnerability in 6Storage Rentals (up to 2.22.0) allows an attacker to send requests from the server to internal resources.
