CVE-2026-97146
Apache YuniKorn 1.9.0 and earlier allows bypassing the check for the user annotation by setting a secondary label on the pod. If the pod has the label 'app=yunikorn' the checks limiting the user annotation content are not run. The label is used to identify the YuniKorn application itself in the deployments.
The bypass allows any user to specify an arbitrary user info annotation. The arbitrary user information could allow access to a queue that the user normally would not have access to. Quota usage for the queue might be impacted if the application runs in the incorrect queue. User based quota enforcement is also based on the user annotation. User quota tracking could be side stepped even if the application runs in the correct queue.

- Explotación
T1203Exploitation for Client Executionexecution75 % - Impacto principal
T1078.001Default Accountsstealth · persistence · privilege escalation · initial access70 % - Impacto secundario
T1552.007Container APIcredential access65 %
Requiere interacción del usuario (UI:P) y acceso en red con privilegios elevados (PR:H). Bypass de etiqueta permite especificar anotación de usuario arbitraria, otorgando acceso a colas restringidas y eludiendo cuotas. Impacto en autenticación/autorización (T1078.001) y evasión de controles de recur
