Description

CVE-2026-13395 is a high-severity SQL injection vulnerability in the Online Scheduling and Appointment Booking System WordPress plugin. Versions before 27.8 do not properly sanitize or cast a user-supplied parameter in unauthenticated front-end booking requests, allowing attackers to perform SQL injection. This can lead to extraction of sensitive data such as password hashes from the database.
