CVE-2026-54247 Skipper: Unbounded Request Body Read in Admission Webhook Causes Memory Exhaustion DoS

Skipper is an HTTP router and reverse proxy for service composition. Prior to 0.26.22, Handler in dataclients/kubernetes/admission/admission.go passes the body of requests to the Kubernetes admission endpoint at :9443/admission directly to io.ReadAllr.Body without a size limit. An attacker with...

CVE-2026-54247

Skipper (Zalando's HTTP router and reverse proxy) contains an unbounded memory allocation in its Kubernetes admission webhook handler (dataclients/kubernetes/admission/admission.go). The handler calls io.ReadAll(r.Body) without enforcing a size limit, so an attacker with in-cluster network access...

CVE-2026-73198 Ipa: freeipa: unauthenticated dos in `/ipa/i18n_messages` via unbounded request body read

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18nmessages endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial o...

CVE-2026-73197 Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the /ipa/migration/migration.py endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increas...

Skipper: Unbounded Request Body Read in Admission Webhook Causes Memory Exhaustion DoS

Summary The Kubernetes admission webhook handler reads the entire request body using io.ReadAllr.Body without any size limit. Any client that can reach the webhook port within the cluster can send a multi-GB payload, causing the skipper process to exhaust memory and be OOM-killed. This disrupts a...

BIT-GRAFANA-2026-33382 Denial of service via unbounded request body size

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service...
