How to fix?

Upgrade Echo:latest sogo to version 5.1.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sogo package and not the sogo package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.)
