CVE-2026-110035 · Severity: info · Published 2026-10-18

The Salon Booking System WordPress plugin fails to properly restrict access to a REST API endpoint that exposes discount coupon information. Any authenticated user, including low-privilege subscribers, can retrieve all coupons configured on a salon website, including those hidden from customers, along with sensitive details like amounts, validity dates, and usage limits. This information disclosure could help attackers craft fraud schemes or bypass promotional restrictions.

## Technical details

A REST API endpoint in the plugin does not enforce role-based access control, allowing any authenticated user to access coupon data intended only for salon staff. The vulnerability requires authentication but no special privileges; a subscriber account is sufficient to retrieve all discount configurations. This is a broken access control issue affecting the /discounts route or similar endpoint that should be staff-restricted.
