Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress: Unauthenticated shortcode injection through customer names
The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.7.0. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The payload is planted during the unauthenticated booking flow and triggered when the Customer Cabinet block rendered by render_customer_dashboard() outputs the stored name into the content stream, where WordPress core's do_shortcode filter at priority 11 re-parses and executes it.

Update, patch or deactivate.
No confirmed fixed release is identified. Disable the affected feature or deactivate the component until an upstream fix is confirmed. Upstream 5.7.3 is available and may resolve this issue, but its changelog does not clearly establish a matching fix; it is not marked safe here. Do not pass stored customer names through shortcode evaluation. Render names as text outside any later do_shortcode pass; restrict the affected booking and Customer Cabinet flow until resolved.
No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
