CVE-2024-40648
MEDIUM4.8EPSS 0.07%`UserIdentity::is_verified` not checking verification status of own user identity while performing the check
發布日:2024/7/18修改日:2024/7/19
描述
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.
