CVE-2026-75885

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).
