The WP Directory Kit WordPress plugin before 1.6.3 does not restrict which database models and columns its public directory-search action may return, nor verify authorisation on it, allowing unauthenticated attackers to read other users' personal data, including email addresses and logins, and private contact-form submissions.

The WP Directory Kit WordPress plugin before 1.6.3 does not sanitise and escape a parameter before using it in a SQL statement, making it possible for users holding the WP Directory Kit WordPress plugin before 1.6.3's custom Listing Admin role, and above, to perform SQL injection attacks.

The WP Directory Kit plugin for WordPress is vulnerable to generic SQL Injection via the 'idfield' parameter in all versions up to, and including, 1.6.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WP Directory Kit plugin for WordPress is vulnerable to time-based SQL Injection via 'displayname' Profile Field (Second-Order) in all versions up to, and including, 1.5.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order injection: a Subscriber stores a displayname containing a single quote via their own profile, which WordPress preserves verbatim; the payload is then triggered when WdkCachedUserEditor::updatelistingsusereditor() re-reads that stored value and passes it unsanitized to the SQL sink.

The WP Directory Kit WordPress plugin before 1.5.8 does not sanitize and escape some of its category and location fields before outputting them in page attributes, allowing users with a WP Directory Kit WordPress plugin before 1.5.8-specific listing-management role (and without the unfilteredhtml capability) to perform Stored Cross-Site Scripting attacks that execute for any visitor of the affected page.

The WP Directory Kit WordPress plugin before 1.5.5 does not perform authorization or nonce checks on one of its authenticated AJAX actions, allowing any authenticated user such as a Subscriber to retrieve stored contact messages and associated user data belonging to other users.

The WP Directory Kit WordPress plugin before 1.5.5 does not perform authorization or nonce checks on one of its authenticated AJAX actions, allowing any authenticated user such as a Subscriber to disclose the WP Directory Kit WordPress plugin before 1.5.5 settings including sensitive API keys and secrets.

The WP Directory Kit plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.4.4 due to incorrect implementation of the authentication algorithm in the "wdkgenerateautologinlink" function. This is due to the feature using a cryptographically weak token generation mechanism. This makes it possible for unauthenticated attackers to gain administrative access and achieve full site takeover via the auto-login endpoint with a predictable token.

The WP Directory Kit plugin for WordPress is vulnerable to SQL Injection via the 'search' parameter in all versions up to, and including, 1.4.6 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WP Directory Kit plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'orderby' parameter in all versions up to, and including, 1.4.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The WP Directory Kit plugin for WordPress is vulnerable to SQL Injection via the 'columnssearch' parameter of the select2ajax() function in all versions up to, and including, 1.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Missing Authorization vulnerability in WPDirectoryKit WP Directory Kit wpdirectorykit allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WP Directory Kit: from n/a through <= 1.2.6.

The WP Directory Kit plugin for WordPress is vulnerable to SQL Injection via the 'attributevalue' and 'attributeid' parameters in all versions up to, and including, 1.3.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
