Details

matrix-sdk-base is the base component to build a Matrix client library. In matrix-sdk-base before 0.14.1, calling the RoomMember::normalized_power_level() method can cause a panic if a room member has a power level of Int::Min. The issue is fixed in matrix-sdk-base 0.14.1. The affected method isn’t used internally, so avoiding calling RoomMember::normalized_power_level() prevents the panic.
