Descriptions

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 es una bifurcación de código abierto impulsada por la comunidad de elasticsearch-ruby. En versiones anteriores a 2.0.1 era usada la función ruby "YAML.load" en lugar de "YAML.safe_load". Como resultado, opensearch-ruby versiones 2.0.0 y anteriores, pueden conllevar a una deserialización no segura usando YAML.load si la respuesta es de tipo YAML. Un atacante debe tener el control de un servidor opensearch y convencer a la víctima de que sea conectado a él para poder explotar esta vulnerabilidad. El problema ha sido parcheado en versión 2.0.1 de la gema opensearch-ruby. Es recomendado a usuarios actualizar. No se presentan mitigaciones conocidas para este problema
