There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - ### Impact When this library is used to deserialize messagepack data from an untrusted source, there is a
    risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions,
    leading to large CPU consumption disproportionate to the size of the data being deserialized. This is
    similar to [a prior advisory](https://github.com/MessagePack-CSharp/MessagePack-
    CSharp/security/advisories/GHSA-7q36-4xx7-xcxf), which provided an inadequate fix for the hash collision
    part of the vulnerability. ### Patches The following steps are required to mitigate this risk. 1. Upgrade
    to a version of the library where a fix is available. 1. Review the steps in [this previous
    advisory](https://github.com/MessagePack-CSharp/MessagePack-
    CSharp/security/advisories/GHSA-7q36-4xx7-xcxf) to ensure you have your application configured for
    untrusted data. ### Workarounds If upgrading MessagePack to a patched version is not an option for you,
    you may apply a manual workaround as follows: 1. Declare a class that derives from `MessagePackSecurity`.
    2. Override the `GetHashCollisionResistantEqualityComparer<T>` method to provide a collision-resistant
    hash function of your own and avoid calling `base.GetHashCollisionResistantEqualityComparer<T>()`. 3.
    Configure a `MessagePackSerializerOptions` with an instance of your derived type by calling `WithSecurity`
    on an existing options object. 4. Use your custom options object for all deserialization operations. This
    may be by setting the `MessagePackSerializer.DefaultOptions` static property, if you call methods that
    rely on this default property, and/or by passing in the options object explicitly to any `Deserialize`
    method. ### References - Learn more about best security practices when reading untrusted data with
