Vulnerability from github – Published: 2024-07-18 15:28 – Updated: 2024-07-19 15:27

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-crypto crate.

Patches

The 0.7.2 release of the matrix-sdk-crypto crate includes a fix.

Workarounds

None.
