Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Reaching this weakness in Booking Calendar 10.15 – 11.8.2 takes an account at Editor level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Booking Calendar the fix is 11.8.3: builds 10.15 – 11.8.2 are affected, anything from 11.8.3 onward is not.
Remediation
Update to version 11.8.3, or a newer patched version
