๐จ CVE-2026-121139
The Rapid7 Metasploit msf-ws suffers from a missing authentication vulnerability whereby the REST API grants an unauthenticated "bootstrap" exemption so that the very first administrator can be created when the users table is empty. While the table is empty, POST /api/v1/users is exempt from authentication by design: the route handler calls warden.authenticate!(scope: :admin_api), which resolves to AdminApiToken. The inherited ApiToken#authenticate! short-circuits and returns success!() whenever msf.auth_initialized is false, without ever evaluating AdminApiToken's administrator check. In that state the endpoint creates a user โ including an administrator โ for an entirely unauthenticated caller.
This issue has been fixed in version 6.5.9.

A security issue was discovered in ingress-nginx where a user with permission to create an Ingress may be able to cause denial of service of the ingress-nginx data plane, or possibly redirect traffic from other Ingresses. Kubernetes clusters are only affected if they are using ingress-nginx.
Due to a missing check, the mirror-target Ingress annotation can be used to target an unauthenticated configuration API within the ingress-nginx controller, allowing write commands to be submitted. Corrupting the data within that configuration API results in all traffic through ingress-nginx being dropped until an Ingress configuration change or a controller restart causes the data to be recreated correctly.
In principle, this write access could also be used to redirect traffic from other Ingresses controlled by the same ingress-nginx instance. In practice, there is negligible additional risk: such redirection would require privileged information about internal ingress-nginx state, and users can already redirect traffic from other Ingresses controlled by the same ingress-nginx anyway.

undici is an HTTP client for Node.js. In versions 7.30.1 and 8.12.2 through 8.12.3, when an originless Agent composes the redirect and shared cache interceptors, undici decides whether to store the final response under the original request key by inspecting only the final redirect hop, which bypasses the earlier fix for CVE-2026-109829 that compared only the initial and final origins. A redirect that bounces through an untrusted origin and returns to the trusted origin is still cached under the trusted key, an intermediate hop's Vary is dropped so a response that varies on Authorization or Cookie can be served to a different user, and an intermediate hop's no-cache or default-uncacheable status is ignored so a non-storable redirect is laundered into a cacheable entry. An attacker who controls a redirect target from a trusted URL can poison the cached entry for that URL or have a private, per-user response served to a later caller. The issue is fixed in undici 7.30.2 and 8.12.4, and users should upgrade to one of those versions or later. As a workaround, compose the interceptors as cache then redirect, use per-origin dispatchers and cache stores, or disable shared caching on redirect-capable requests.

undici is an HTTP client for Node.js. In versions 7.0.0 through 7.30.1 and 8.0.0 through 8.12.3, the redirect interceptor strips sensitive headers such as Authorization, Cookie, Proxy-Authorization, and Host when a request is redirected to a different origin, but when request headers are supplied as an array of name and value tuples (a valid documented input, for example from Object.entries), the redirect handler misreads them as a flat list so the header names never match and the sensitive headers are not removed. If a header-normalizing interceptor such as cache or deduplicate is composed outside the redirect interceptor, it then serializes the retained headers onto the cross-origin request, disclosing the caller's origin-bound credentials to the unrelated redirect destination. This is a representation-dependent bypass of the cross-origin header stripping added in CVE-2024-30260. The issue is fixed in undici 7.30.2 and 8.12.4, and users should upgrade to one of those versions or later.
