CVE-2026-90455

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.

之前的一次更新将捆绑的 HTTP 客户端库升级到可修复已知漏洞的版本，但该更新后来被回滚，导致早期存在漏洞的版本重新引入了日志处理组件中。该组件中唯一使用此库的代码路径仅在初始化时向一个固定的、可信的供应商 URL 发起请求，且不会通过该库处理攻击者控制的输入，因此在该上下文中，重新引入的漏洞版本的实际可利用性受到限制。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library, limiting practical exploitability of the reintroduced version in this context.
