GMS-2023-7: 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 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.
