Unsafe YAML deserialization in opensearch-ruby

opensearch-ruby is a community-driven, open source fork of elasticsearch-ruby. In versions prior to 2.0.1 the ruby `YAML.load` function was used instead of `YAML.safe_load`. As a result opensearch-ruby 2.0.0 and prior can lead to unsafe deserialization using YAML.load if the response is of type YAML. An attacker must be in control of an opensearch server and convince the victim to connect to it in order to exploit this vulnerability. The problem has been patched in opensearch-ruby gem version 2.0.1. Users are advised to upgrade. There are no known workarounds for this issue.

opensearch-ruby 代码问题漏洞

opensearch-ruby是opensearch-project开源的一个用于 OpenSearch 的 Ruby 客户端。 opensearch-ruby存在代码问题漏洞，该漏洞源于在 2.0.1 之前的版本中，使用 ruby `YAML.load` 函数而不是 `YAML.safe_load`。因此，如果响应是 YAML 类型，opensearch-ruby 2.0.0 和之前的版本可能会导致使用 YAML.load 进行不安全的反序列化。 攻击者必须控制一个 opensearch 服务器并说服受
