  - SOGo 2.x before 2.4.1 and 3.x through 5.x before 5.1.1 does not validate the signatures of any SAML
    assertions it receives. Any actor with network access to the deployment could impersonate users when SAML
    is the authentication method. (Only versions after 2.0.5a are affected.) (CVE-2021-33054)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
