Summary
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.
Risk Assessment
The risk includes potential injection of malicious scripts that execute in the user's browser, which could lead to data theft, session hijacking, or other attacks.
Recommendation
Update the LatePoint plugin to the latest version that contains the fix. Also restrict user privileges to the necessary minimum.
Other vulnerabilities in LatePoint
See all- CVE-2026-5356High
The LatePoint plugin for WordPress up to version 5.4.0 has an improper input validation vulnerability in the Stripe Connect payment processor. This allows unauthenticated attackers to pay arbitrary amounts by supplying a previously successful PaymentIntent token.
- CVE-2026-57714Critical
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.
- CVE-2026-11398Medium
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.
- CVE-2026-12657Medium
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.
- CVE-2026-49083High
LatePoint versions up to 5.5.1 contain a vulnerability that allows privilege escalation for contributors.
- CVE-2026-7652Medium
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.
