Atomic Edge analysis of CVE-2025-69366 (metadata-based):
This vulnerability is an unauthenticated SQL injection in the Emerce Core WordPress plugin version 1.8 and earlier. The flaw allows attackers to inject arbitrary SQL commands via a user-supplied parameter, enabling sensitive database information extraction. The CVSS 3.1 score of 7.5 (High) reflects its network-accessible attack vector, low attack complexity, and high confidentiality impact.

Atomic Edge research indicates the root cause is insufficient escaping of user input combined with inadequate query preparation. The vulnerability description explicitly states “insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.” This matches CWE-89 patterns where WordPress plugins directly interpolate unsanitized user input into SQL statements without using proper `$wpdb->prepare()` methods. Without source code, this conclusion is inferred from the CWE classification and vulnerability description.

Exploitation likely occurs through a public-facing endpoint that accepts user input for database queries. Common WordPress patterns suggest an AJAX handler (`admin-ajax.php` or `admin-post.php`) with an action parameter like `emerce_core_action` or a REST API endpoint under `/wp-json/emerce-core/`. Attackers would send crafted HTTP requests containing SQL injection payloads in specific parameters. Example payloads include UNION-based queries for data extraction or time-based blind SQLi techniques using `SLEEP()` or `BENCHMARK()` functions.

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. All user-supplied parameters must be validated against expected data types and sanitized using appropriate WordPress sanitization functions. The fix should also implement proper capability checks to restrict database operations to authorized users.

Successful exploitation enables complete database compromise. Attackers can extract sensitive information including WordPress user credentials (hashed passwords), personally identifiable information, payment details, and other business-critical data stored in the database. While the CVSS vector indicates no integrity or availability impact, SQL injection often enables privilege escalation and subsequent site takeover through admin credential theft or direct database modification.
