What is CVE-2026-105256?

The LatePoint plugin for WordPress prior to version 5.7.5 contains a significant input validation flaw. This vulnerability allows an unauthenticated visitor to manipulate the client-supplied booking charge parameters, potentially lowering the amount due to zero. As a result, the attacker can secure a confirmed appointment and create a recorded order without making any payment. This could lead to unauthorized services being rendered and financial implications for the business.

Affected Version(s)

LatePoint 0 < 5.7.5
