Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 OpenBao 2.6.4 之前的版本以及 2.7.x 系列中 2.7.1 之前的版本里，AppRole 身份验证方法在使用 Secret ID 时未检查其是否已过期，导致过期的 Secret ID 在定期清理（tidy）操作将其移除前依然有效。持有此类已过期但尚未被清理的 Secret ID 的攻击者可以成功登录，并在其预设的生存时间（TTL）之外持续获得访问权限。
