Description
The Chaty Pro plugin for WordPress is vulnerable to Authenticated Time-Based Blind SQL Injection in versions up to and including 3.5.5. This is due to the fetch_custom_field() function in admin/class-admin-base.php retrieving the widget_id POST parameter via filter_input(INPUT_POST, ...) and directly concatenating the value into a raw SQL query in a numeric context without using $wpdb->prepare() or any integer casting. Additionally, the nonce verification check is performed after the SQL query has already executed, providing no protection against the injection. This makes it possible for authenticated attackers with subscriber-level access and above to inject arbitrary SQL commands, potentially leading to unauthorized extraction of sensitive database contents including user credentials and configuration data.

AI Analysis

Impact

The Chaty Pro plugin for WordPress contains an Authenticated Time‑Based Blind SQL Injection vulnerability that occurs when the widget_id POST parameter is unsafely concatenated into a raw SQL query within admin/class-admin-base.php. The nonce verification is performed after the query, giving attackers no protection. The flaw allows subscribers and higher‑privileged users to inject arbitrary SQL statements, potentially retrieving sensitive database contents such as user credentials and configuration data.

Affected Systems

Chaty Pro plugin, WordPress, versions up to and including 3.5.5. Authenticated users possessing the subscriber role or higher can exploit the flaw.

Risk and Exploitability

The CVSS score of 6.5 places this issue in the medium‑severity range, and the EPSS score of less than 1% suggests low likelihood of widespread exploitation at present. It is not listed in the CISA KEV catalog. Attackers must be logged into the WordPress site with a subscriber or higher role and must be able to send crafted POST requests to the widget management endpoint. Upon exploitation, the attacker can retrieve or manipulate database rows, jeopardizing confidentiality and integrity of stored data.
