What is CVE-2023-35116?
CVE-2023-35116 is a medium-severity denial of service vulnerability in Fasterxml Jackson-Databind, published on 14 Jun 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
jackson-databind through 2.15.2 allows attackers to cause a denial of service or other unspecified impact via a crafted object that uses cyclic dependencies. NOTE: the vendor's perspective is that this is not a valid vulnerability report, because the steps of constructing a cyclic data structure and trying to serialize it cannot be achieved by an external attacker.
Weakness: CWE-770
