CVE-2026-77393— Inductive Automation Ignition Incorrect Default Permissions

Quick assessment

Affected
Inductive Automation Ignition
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 Ignition 8.1.53 及更早版本中，网关的“创建项目角色”设置默认值为空，这意味着任何经过身份验证的用户都可以创建项目（前提是能够执行网关脚本）。Ignition 8.1.54 将项目创建权限限制在 Designer 会话中，不再依赖该设置。8.3 系列不受此问题影响。
