Technical details
The vulnerability is an Insecure Direct Object Reference (IDOR) in the LatePointAbilityDeleteBooking::execute method, affecting versions up to 5.6.3. The flaw stems from missing validation of user-controlled booking IDs, allowing attackers with LatePoint Agent-level access or higher to enumerate and manipulate arbitrary bookings. An authenticated attacker can read booking details and PII, or delete bookings, by supplying any valid booking ID. Exploitation requires that administrators have enabled the Abilities API toggles (latepoint_abilities_api, latepoint_abilities_api_delete, and/or latepoint_abilities_api_edit) in plugin settings. Patch availability was not indicated in the advisory.
