CVE-2026-75885— Openshift/console: openshift/console: unauthenticated ssrf and resource exhaustion via devfile parser endpoint

Quick assessment

Affected
Red Hat Red Hat OpenShift Container Platform 4
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.

OpenShift 控制台存在一个缺陷。对 和 端点未经验证的访问允许远程攻击者发送精心构造的 devfile 负载。这可能导致服务器端请求伪造（SSRF），即控制台 Pod 向内部服务发起请求，并将部分响应内容返回给攻击者。此外，攻击者还可以通过发送未指定内容长度的重复大请求，导致内存无限制增长，从而引发拒绝服务（DoS）攻击。

Vulnerability Title
Openshift/console: openshift/console: unauthenticated ssrf and resource exhaustion via devfile parser endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the OpenShift console. Unauthenticated access to the `/api/devfile/` and `/api/devfile/samples/` endpoints allows a remote attacker to send crafted devfile payloads. This can lead to Server-Side Request Forgery (SSRF), where the console pod makes requests to internal services and reflects partial responses to the attacker. Additionally, by sending repeated large requests without a specified content length, an attacker can cause unbounded memory growth, leading to a Denial of Service (DoS).
