Does this matter?
Lower severity and a low EPSS score (1.93%). Track it; it rarely justifies an emergency change on its own.
Description
Apache Guacamole 1.3.0 and older may incorrectly include a private tunnel identifier in the non-private details of some REST responses. This may allow an authenticated user who already has permission to access a particular connection to read from or interact with another user's active use of that same connection.
