Description

The Meow Gallery WordPress plugin before 4.1.9 does not sanitise, validate or escape the ids attribute of its gallery shortcode (available for users as low as Contributor) before using it in an SQL statement, leading to an authenticated SQL Injection issue. The injection also allows the returned values to be manipulated in a way that could lead to data disclosure and arbitrary objects to be deserialized.

• 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.
