If the user had set up a WPA Enterprise or 802.1x connection that used a CA certificate to verify the identity of the network to which the user was connecting, and the user deleted or moved that CA certificate file at a later point, NetworkManager will still connect to that network but without using the CA certificate.  This could result in connections to a rogue network that is spoofing the original network as the identity of the network is not verified with the CA certificate after the certificate has been deleted.

Obviously requires direct interaction by the user that configured the connection in the first place to remove the CA certificate file.
