-----------------------------------------
Summary: Critical security vulnerability in snakeyaml
Key: CONFIGURATION-829
URL: https://issues.apache.org/jira/browse/CONFIGURATION-829
Project: Commons Configuration
Issue Type: Bug
Components: File reloading
Affects Versions: 2.8.0
Reporter: Aaron Coady
This vulnerability is fixed in snakeyaml 2.0 and requires a backwards
incompatible change in the constructor
[https://nvd.nist.gov/vuln/detail/CVE-2022-1471]
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.
