Description

The Contest Gallery WordPress plugin before 13.1.0.6 does not have capability checks and does not sanitise or escape the cg-search-user-name-original parameter before using it in a SQL statement when exporting users from a gallery, which could allow unauthenticated to perform SQL injections attacks, as well as get the list of all users registered on the blog, including their username and email address

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
