Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Open Access Management（OpenAM）是一种访问管理解决方案。在 16.1.1 版本之前，OAuthTokenStore 会从共享的核心令牌存储（CTS）中读取由调用方提供的令牌标识符，且未限定为仅限 OAuth 的命名空间；同时，OAuthAdapter 会接受那些其 BLOB 声称包含 OAuth 令牌的数据行，但既未绑定受信任的 CTS 类型，也未验证其完整性。 攻击者若能在 CTS 中针对已知的令牌标识符写入可控的 JSON 数据（例如，通过“推送注册”操作后，在已启用该领域的情况下，

Vulnerability Title
OpenAM Arbitrary OAuth Token Minting via Push Registration
Source: CVE Program / CVE List V5
Vulnerability Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, OAuthTokenStore reads caller-supplied token identifiers from the shared Core Token Store (CTS) without an OAuth-only namespace, and OAuthAdapter accepts a row whose BLOB claims to contain an OAuth token without binding the trusted CTS type or verifying integrity. An attacker who can place controlled JSON in CTS under a known token identifier, such as through Push Registration followed by an anonymous SNS callback in an enabled realm, can mint OAuth bearer tokens and OpenID Connect ID tokens with chosen subject, client, realm, and scope. The flaw does not by itself create an OpenAM SSO session or grant console access. This issue is fixed in version 16.1.1.
