SnakeYaml.Constructor.deserialization.RCE

Description

This indicates an attack attempt to remote code execution.
SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization.

Affected Products
