Input validation vulnerability in Wp tabber widget 4.0

The Wp tabber widget plugin used for WordPress has a security issue that allows hackers to access sensitive information from the database. This is because the plugin does not properly protect against SQL injection attacks. This vulnerability affects versions up to and including 4.0. Attackers with contributor-level access or higher can exploit this vulnerability to add their own SQL queries to the existing ones, giving them access to private data.
