- Summary
- matrix-sdk-crypto's `UserIdentity::is_verified` not checking verification status of own user identity while performing the check
- Details
-
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.Impact
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-cryptocrate.Patches
The 0.7.2 release of the
matrix-sdk-cryptocrate includes a fix.Workarounds
None.
