Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Capgo是CAPGO公司的一个专为CapacitorJS开发者打造的移动应用开发和更新平台。 Capgo 12.128.2之前版本存在授权问题漏洞，该漏洞源于middlewareKey函数中未能通过x-limited-key-id标头强制执行对子密钥的limited_to_orgs和limited_to_apps限制，攻击者可引用自己的子密钥绕过子密钥范围限制，导致所有下游路由处理程序使用无限制的父密钥而非作用域子密钥。

Vulnerability Title
Capgo - Subkey Scope Bypass in middlewareKey via x-limited-key-id Header
Source: CVE Program / CVE List V5
Vulnerability Description
Capgo before 12.128.2 fails to enforce limited_to_orgs and limited_to_apps constraints on subkeys provided via x-limited-key-id header in middlewareKey function. Attackers can bypass subkey scope restrictions by referencing their own subkeys, causing all downstream route handlers to use the unrestricted parent key instead of the scoped subkey.
