Technical description

The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference / Missing Authorization in versions up to, and including, 5.7.2. This is due to the publicly reachable steps__start and steps__load_step routes accepting a params[presets][order_item_id] value that is copied verbatim into the booking object without verifying that the referenced order item belongs to the current customer, is a bundle item, is paid, or has remaining capacity — the is_bundle_scheduling() bundle discriminator is a mere !empty(order_item_id) truthiness check, and the code flow explicitly removes the customer and payment steps when this is truthy (the source even carries a TODO acknowledging the missing validation). This makes it possible for unauthenticated attackers to create approved appointments against other customers' order items and to read those customers' names, email addresses, and order codes returned in the booking confirmation.

———A cross-account authorization vulnerability in Zimbra Collaboration Suite (ZCS) allows an authenticated user to insert forged shared-file records into another user's mailbox through FileSharedWithMeRequest. The request bypasses delegated-account authorization and accepts attacker-selected file metadata, owner identifiers and declared sizes without validating a corresponding document share. An attacker can plant entries attributed to another real local account without that account sharing a document. No victim interaction is required. ZCS 10.1.16 and 10.1.20 are affected.5h CVE-2026-1157254.2 MED
