Improper neutralization of special elements used in an SQL command ('SQL injection') vulnerability in wp-post-author. This issue affects wp-post-author version 4.0.0 prior to 4.1.0.

The wp-post-author plugin contains an SQL injection vulnerability caused by improper neutralization of special elements in SQL commands. This issue affects versions before 4.1.0.

The WP Post Author plugin by AF themes contains a blind SQL injection vulnerability. The issue affects versions up to and including 4.0.0.

The WP Post Author plugin for WordPress is vulnerable to generic SQL Injection via the 'wpma_metabox_authors_list' parameter in all versions up to and including 3.9.1. Authenticated attackers with author-level access can append additional SQL queries to extract sensitive information from the database. Exploitation is a two-step chain involving saving a crafted guest-author token and triggering the injection when an admin loads the post list screen.

The WP Post Author plugin version 3.9.1 and earlier contains a SQL injection vulnerability in the Contributor function. This allows an attacker to manipulate database queries.
