CVE-2026-26056
HighSummary
W wersjach 0.19.0 i wcześniejszych w komponencie Air Traffic Controller (ATC) narzędzia Yoke występuje podatność, która pozwala użytkownikom z uprawnieniami do tworzenia/aktualizacji CR na wykonywanie dowolnego kodu WASM. Możliwe jest to poprzez wstrzyknięcie złośliwego adresu URL za pomocą adnotacji overrides.yoke.cd/flight.
Risk Assessment
Podatność ta umożliwia atakującym tworzenie dowolnych zasobów Kubernetes oraz potencjalne podniesienie uprawnień do poziomu cluster-admin, co stanowi poważne zagrożenie dla bezpieczeństwa infrastruktury.
Recommendation
Zaleca się aktualizację Yoke do wersji, w której ta podatność została naprawiona, oraz wdrożenie odpowiednich mechanizmów walidacji adresów URL w adnotacjach.

Original NVD description (English source)
Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer. In 0.19.0 and earlier, a vulnerability exists in the Air Traffic Controller (ATC) component of Yoke. It allows users with CR create/update permissions to execute arbitrary WASM code in the ATC controller context by injecting a malicious URL through the overrides.yoke.cd/flight annotation. The ATC controller downloads and executes the WASM module without proper URL validation, enabling attackers to create arbitrary Kubernetes resources or potentially escalate privileges to cluster-admin level.
