What is CVE-2020-36185?

A deserialization vulnerability exists in FasterXML's jackson-databind library, specifically in versions prior to 2.9.10.8. This issue arises due to improper handling of serialization gadgets, which can allow an attacker to control object parameters during deserialization. This may lead to unexpected behavior in applications that rely on jackson-databind for JSON processing, particularly when integrating with org.apache.tomcat.dbcp2.datasources.SharedPoolDataSource.
