SQL injection vulnerability in includes/ym-download_functions.include.php in the Code Futures YourMembers plugin for WordPress allows remote attackers to execute arbitrary SQL commands via the ym_download_id parameter to the default URI.
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.
