Affected packages

• crates.io model: <= 0.1.2 (no fix yet)

Description

`Shared` data structure in `model` crate implements `Send` and `Sync` traits regardless of the inner type. This allows safe Rust code to trigger a data race, which is undefined behavior in Rust. Users are advised to treat `Shared` as an unsafe type. It should not be used outside of the testing context, and care must be taken so that the testing code does not have a data race besides a race condition that is expected to be caught by the test.
