Name of the Vulnerable Software and Affected Versions Up down image slideshow gallery plugin for WordPress versions up to, and including, 12.0

Description The issue arises from insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the plugin's shortcode, making it possible for authenticated attackers with subscriber-level and above permissions to append additional SQL queries into already existing queries. This can be used to extract sensitive information from the database.

Recommendations For versions up to, and including, 12.0, consider disabling the shortcode functionality until a patch is available to prevent exploitation. Restrict access to the plugin's configuration to minimize the risk of exploitation by authenticated attackers.
