CVE-2026-5356

The LatePoint plugin for WordPress contains a Blind SQL Injection vulnerability due to improper neutralization of special elements in SQL commands. This issue affects versions up to and including 5.6.3.

The LatePoint plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'btn_wrapper_classes' attribute of the 'latepoint_resources' shortcode in all versions up to, and including, 5.3.2. This is due to insufficient input sanitization and output escaping in the 'locations' branch of the 'shortcode_latepoint_resources' function. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The LatePoint plugin for WordPress up to version 5.6.1 is vulnerable to authorization bypass. Unauthenticated attackers can modify personally identifiable information (first name, last name, phone number, and notes) of any existing customer record, including administrator accounts, by submitting the booking form with a known email address. Exploitation requires guest bookings to be enabled.

The LatePoint plugin for WordPress up to version 5.6.2 is vulnerable to Insecure Direct Object Reference (IDOR) via the 'service_id' parameter. Missing validation allows unauthenticated attackers to create approved bookings for admin/agent-only services, consuming restricted capacity.

LatePoint versions up to 5.5.1 contain a vulnerability that allows privilege escalation for contributors.

The LatePoint plugin for WordPress up to version 5.5.0 is vulnerable to account takeover due to a weak password recovery mechanism in the unauthenticated guest booking flow. The save_connected_wordpress_user() function propagates a LatePoint customer's email to the linked WordPress user account without ownership verification, and the guest booking flow can overwrite an existing customer's email via phone-based merge without authentication.
