Atomic Edge analysis of CVE-2025-69308 (metadata-based):
This vulnerability is an unauthenticated SQL injection in the Nestbyte Core WordPress plugin version 1.2 and earlier. The flaw allows attackers to inject arbitrary SQL commands via a user-supplied parameter, leading to sensitive database information disclosure. The CVSS score of 7.5 (High) reflects its network-accessible attack vector, low attack complexity, and high confidentiality impact.

Atomic Edge research identifies the root cause as improper neutralization of special elements in SQL commands (CWE-89). The vulnerability description explicitly states insufficient escaping on user-supplied parameters and lack of sufficient preparation on existing SQL queries. This indicates the plugin likely constructs SQL queries by directly concatenating unsanitized user input without using WordPress’s $wpdb->prepare() method or proper parameterized statements. These conclusions are inferred from the CWE classification and vulnerability description, as source code is unavailable for confirmation.

Exploitation occurs through unauthenticated HTTP requests to WordPress endpoints that process the vulnerable parameter. Based on WordPress plugin patterns, the attack vector is likely an AJAX handler (wp-admin/admin-ajax.php) or a REST API endpoint that accepts user input. Attackers would send crafted payloads containing SQL injection characters like single quotes, comment sequences, or UNION SELECT statements. A typical payload might append a UNION SELECT query to extract user credentials from the wp_users table.

Remediation requires implementing proper input validation and parameterized queries. The plugin should use WordPress’s $wpdb->prepare() method for all SQL queries incorporating user input. Input validation should include type checking, length limits, and allowlisting acceptable characters. The fix must also ensure proper capability checks exist for any administrative database operations. These recommendations follow WordPress security best practices for SQL injection prevention.

Successful exploitation enables complete database compromise. Attackers can extract sensitive information including WordPress user credentials (hashed passwords), personally identifiable information, plugin-specific data, and site configuration details. This data exposure can lead to subsequent attacks like password cracking, privilege escalation, or site takeover. The vulnerability does not directly enable remote code execution or integrity/availability impacts according to the CVSS vector.
