The UserIdentity::is_verified() method in the matrix-sdk-crypto crate before
version 0.7.2 doesn't take into account the verification status of the user's
own identity while performing the check and may as a result return a value
contrary to what is implied by its name and documentation.
If the method is used to decide whether to perform sensitive operations towards a user identity, a malicious homeserver could manipulate the outcome in order to make the identity appear trusted. This is not a typical usage of the method, which lowers the impact. The method itself is not used inside the matrix-sdk-crypto crate.
