CVE-2026-75885
SUMMARY

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).

CVE-2026-93894
SUMMARY

In Vinyl Cache before 9.0,2, workspace buffer overflow vulnerability was found in the .upper() and .lower() string type methods of VCL. This can be used as a remote denial of service (DoS) vector to make the child process segfault or assert, and then restart. Effectively exploiting this vulnerability requires prior knowledge about the VCL in use and the ability to craft a request that contains a string that is long enough to fill the remaining workspace at the call site while staying under the different request size limits (http_req_size, http_req_hdr_len, etc.).
