What is CVE-2025-8692?

The Coupon API plugin for WordPress is susceptible to SQL Injection through the 'log_duration' parameter, affecting all versions up through 6.2.9. This vulnerability arises from inadequate escaping of user-supplied inputs as well as insufficient preparation in existing SQL queries. As a result, authenticated attackers with Administrator-level access can manipulate SQL queries by appending their own commands, potentially extracting sensitive data from the database.
