CVE-2026-90449

Quick assessment

Affected
CISA Malcolm
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.

当配置了特定的认证模式时，反向代理会将发往内置第三方管理界面的请求直接转发到该界面，而不会先应用网关自身的认证要求。对于该管理界面——它负责管理用于控制部署中所有其他服务的凭证存储——其全部访问控制完全委托给该第三方界面自身的登录机制。因此，该内置界面存在的任何认证漏洞都可能危及保护整个部署的凭证存储。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
When a particular authentication mode is configured, the reverse proxy forwards requests for a bundled third-party administrative interface directly to that interface without applying the gateway's own authentication requirement first. All access control for this administrative interface, which manages the credential store used to gate every other service in the deployment, is delegated entirely to that third-party interface's own login mechanism. Any authentication weakness in that bundled interface would compromise the credential store protecting the rest of the deployment.
