优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

Apache Camel PQC 组件存在默认权限设置不当的漏洞。 该问题影响以下版本的 Apache Camel： 4.12.0 至 4.18.5（不含 4.18.5） 4.19.0 至 4.22.1（不含 4.22.1） 当该组件将生成的密钥材料写入磁盘时，使用的是进程默认 umask 所产生的文件权限，而非将文件权限限制为仅所有者可访问。若宿主系统的 umask 允许组或所有用户读取，则私钥将可被其他本地账户读取。该漏洞的暴露对象为本地攻击者，而非 Camel 威胁模型中主要关注的远程发送方，因此严重性评估为

Vulnerability Title
Apache Camel: Camel-PQC Private Key Disclosure via Key Material Written with Default File Permissions
来源: CVE Program / CVE List V5
Vulnerability Description
Incorrect Default Permissions vulnerability in Apache Camel PQC component. This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1. When the component wrote generated key material to disk it did so with the permissions the process default umask produced, rather than restricting the file to its owner. On a host whose umask allows group or world read, the private key was therefore readable by other local accounts. The exposure is to a local party rather than to the remote sender that the Camel threat model treats as the primary adversary, which is why the severity is assessed low, but the consequence where it applies is complete: possession of the private key defeats every signature and key exchange the deployment performs with it. 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. Key material is now written with owner-only permissions. For deployments that cannot upgrade immediately, place the key directory on a path only the service account can traverse, and tighten the process umask. Key material already written with permissive permissions should be treated as exposed and rotated.
