CVE-2026-74037— Wazuh 4.0.0 before 4.14.8 Session Invalidation Bypass in check_token

Quick assessment

Affected
Wazuh wazuh-manager
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 Wazuh 4.14.8 之前的 4.0.0 版本中，对于具有零个静态角色的 run_as 用户，系统未能使已签发的令牌失效，因为 check_token 函数从未检查黑名单。获得撤销的管理员权限的攻击者仍可继续通过身份验证，并将管理员角色自我链接，从而永久保留特权访问权限。
