## Affected

- wordpresschef Salon Booking System – Free Version: through 10.30.25

## Description

The Salon Booking System – Free Version plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 10.30.25. This is due to the public booking flow accepting attacker-controlled file-field values and later using those stored values as trusted paths for email attachments. This makes it possible for unauthenticated attackers to read arbitrary local files and exfiltrate them via booking confirmation email attachments.
