Apache Camel Shiro 组件存在身份验证不当漏洞。 该问题影响 Apache Camel 的以下版本范围： 4.0.0 至 4.18.5（不含 4.18.5） 4.19.0 至 4.22.1（不含 4.22.1） 漏洞成因：Shiro 安全处理器在检测到当前线程已绑定的主体（Subject）所携带的主体名（Principal）与传入交换（Exchange）中的主体名一致时，会跳过凭证验证。由于承载 Camel 交换的线程来自线程池并在不同交换间复用，若此前某个已认证的交换在退出时未清除其绑定的主体，该

Vulnerability Title
Apache Camel: Camel-Shiro Authentication Bypass via Skipped Credential Verification on Subject Reuse
来源: CVE Program / CVE List V5
Vulnerability Description
Improper Authentication vulnerability in Apache Camel Shiro component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Shiro security processor skipped credential verification when the subject already bound to the current thread carried the same principal as the incoming exchange. Because the thread that carries a Camel exchange is drawn from a pool and reused across exchanges, a subject left bound by an earlier authenticated exchange could satisfy the check for a later one that presented no valid credentials of its own. The password on the incoming exchange was, in that case, never verified. The condition depends on thread reuse and on the principal matching, which is why it is not reached on every request, but it requires nothing of the attacker beyond sending a request naming a principal that is in active use. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The processor now verifies the presented credentials on every exchange rather than accepting a subject already bound to the thread. Setting alwaysReauthenticate=false restores the previous behaviour for deployments that depend on it. For deployments that cannot upgrade immediately, ensure the Shiro subject is cleared from the thread at the end of every exchange so that no subject can be inherited by a later one.
