CVE-2026-90448

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.

某部署模式旨在仅暴露对存储数据的只读访问，但其代理的一组应用程序编程接口（API）路由未限制允许使用的请求方法。其中一个路由接受用于创建或覆盖存储记录（包括由攻击者选定的标识符）的请求，并使用了应用程序自身具有更高权限的后端凭据。这使得在原本设计为只读部署中，经过身份验证的用户能够伪造或覆盖本不应在该部署模式下被修改的存储记录。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, including an attacker-chosen identifier, using the application's own elevated backend credentials. This allows an authenticated user on a deployment intended to be read-only to forge or overwrite stored records that should not be modifiable in that deployment mode.
