Issue with whitespace in JWT roles in OpenSearch

OpenSearch is an open source distributed and RESTful search engine. OpenSearch uses JWTs to store role claims obtained from the Identity Provider (IdP) when the authentication backend is SAML or OpenID Connect. There is an issue in how those claims are processed from the JWTs where the leading and trailing whitespace is trimmed, allowing users to potentially claim roles they are not assigned to if any role matches the whitespace-stripped version of the roles they are a member of. This issue is only present for authenticated users, and it requires either the existence of roles that match, not considering leading/trailing whitespace, or the ability for users to create said matching roles. In addition, the Identity Provider must allow leading and trailing spaces in role names. OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1 are affected. Users are advised to upgrade to OpenSearch 1.3.8 or 2.5.0. There are no known workarounds for this issue.

认证机制不恰当

OpenSearch Project 授权问题漏洞

OpenSearch Project是OpenSearch Project开源的一个社区驱动的、Apache 2.0许可的开放源代码搜索和分析套件。使其易于获取、搜索、可视化和分析数据。 OpenSearch 1.0.0版本至1.3.7版本、2.0.0版本至2.4.1版本存在授权问题漏洞，该漏洞源于在JWT中前导空格和尾随空格会被删除，如果用户创建的角色与他们所属角色的空白删除版本相同，则允许用户使用未分配给他们的角色。
