Vulnerability Details

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5crp-9r3c-p9vr. This link is maintained to preserve external references. Original Description Newtonsoft.Json before version 13.0.1 is affected by a mishandling of exceptional conditions vulnerability.
