26th percentile - higher than 26% of all known CVEs

Summary

The Online Scheduling and Appointment Booking System WordPress plugin before version 27.8 does not sanitize or properly cast a user-supplied parameter from its unauthenticated front-end booking requests before using it in a SQL query. This allows unauthenticated attackers to perform SQL injection attacks and extract sensitive data such as password hashes from the database.

Risk Assessment

Unauthenticated attackers can gain full access to the database, including user password hashes, potentially leading to complete site takeover and data theft.

Recommendation

Immediately update the Online Scheduling and Appointment Booking System plugin to version 27.8 or later, which includes proper input sanitization.
