Hi,

The following vulnerabilities were published for guacamole-client.

CVE-2021-41767[0]:
| 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.

CVE-2021-43999[1]:
| Apache Guacamole 1.2.0 and 1.3.0 do not properly validate responses
| received from a SAML identity provider. If SAML support is enabled,
| this may allow a malicious user to assume the identity of another
| Guacamole user.

CVE-2020-11997[2]:
| Apache Guacamole 1.2.0 and earlier do not consistently restrict access
| to connection history based on user visibility. If multiple users
| share access to the same connection, those users may be able to see
| which other users have accessed that connection, as well as the IP
| addresses from which that connection was accessed, even if those users
| do not otherwise have permission to see other users.
