CVE-2026-86091— ntopng before 6.7.260717 Missing Authorization on the Host Pool Bulk Delete Handler

Quick assessment

Affected
ntop ntopng
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.

ntopng 在 6.7.260717 之前的版本中，池（pools）批量删除端点未检查用户权限，使得经过身份验证的非管理员用户能够删除所有主机池及其成员绑定关系。攻击者可以向删除池端点发送 POST 请求，不可逆地销毁所有主机池，从而移除流量策略绑定和可见性限制，这可能绕过安全策略。
