Apiman Manager API affected by Jackson denial of service vulnerability
### Impact
Due to a vulnerability in `jackson-databind <= 2.12.6.0`, an authenticated attacker could craft an Apiman policy configuration which, when saved, may cause a denial of service on the Apiman Manager API.
This does **not** affect the Apiman Gateway.
### Patches
Upgrade to Apiman 3.0.0.Final or later.
If you are using an older version of Apiman and need to remain on that version, contact your Apiman support provider
https://www.apiman.io/support.html for advice/long-term support.
### Workarounds
If all users of the Apiman Manager are trusted then you may assess this is low risk, as an account is required to exploit the vulnerability.
