CVE-2022-1471

Published: Dec 1, 2022

Modified: Jun 18, 2025

PUBLISHED

CVSS v3.1

8.3

HIGH

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.
