FKIE_CVE-2025-29922

Vulnerability from fkie_nvd - Published: 2025-03-20 18:15 - Updated: 2026-06-17 09:05
Summary
kcp is a Kubernetes-like control plane for form-factors and use-cases beyond Kubernetes and container workloads. Prior to 0.26.3, the identified vulnerability allows creating or deleting an object via the APIExport VirtualWorkspace in any arbitrary target workspace for pre-existing resources. By design, this should only be allowed when the workspace owner decides to give access to an API provider by creating an APIBinding. With this vulnerability, it is possible for an attacker to create and delete objects even if none of these requirements are satisfied, i.e. even if there is no APIBinding in that workspace at all or the workspace owner has created an APIBinding, but rejected a permission claim. A fix for this issue has been identified and has been published with kcp 0.26.3 and 0.27.0.

Antes de la versi\u00f3n 0.26.3, la vulnerabilidad identificada permit\u00eda crear o eliminar un objeto mediante APIExport VirtualWorkspace en cualquier espacio de trabajo de destino arbitrario para recursos preexistentes. Por dise\u00f1o, esto solo deber\u00eda permitirse cuando el propietario del espacio de trabajo decide otorgar acceso a un proveedor de API mediante la creaci\u00f3n de un APIBinding. Con esta vulnerabilidad, un atacante puede crear y eliminar objetos incluso si no se cumple ninguno de estos requisitos; es decir, incluso si no existe ning\u00fan APIBinding en ese espacio de trabajo o si el propietario del espacio de trabajo ha creado un APIBinding, pero ha rechazado una solicitud de permiso. Se ha identificado una soluci\u00f3n para este problema y se ha publicado en kcp 0.26.3 y 0.27.0."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
