• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-01 · updated 2026-10-25
• Weakness: CWE-89

Description

The BookingPress Appointment Booking Pro plugin for WordPress is vulnerable to SQL Injection via the 'store_service_date' parameter of the bpa_assign_staffmember_to_slots() function in versions up to and including 5.7.1. This is due to the explicit use of stripslashes_deep() on user-supplied POST data before it is interpolated verbatim into a SQL LIKE clause without use of $wpdb->prepare() or any parameterization. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
