CVE-2022-1471
HIGH8.3EPSS 93.8%SnakeYaml Constructor Deserialization Remote Code Execution
Published: 12/12/2022Modified: 4/28/2026
Description
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. We recommend upgrading to version 2.0 and beyond.
