- Around line 785-797: Update the metrics useEffect around updateMetrics to
return immediately when flagPending(canGetNS) is true, preventing fetches,
dispatches, and interval polling while the flag is unresolved. Add an
effect-scoped active/cleanup guard so resolved requests do not dispatch after
cleanup; preserve the existing namespace metrics selection and 30-second polling
once canGetNS is settled.

Is this data trusted, i.e., there is no injection risk here?

I guess the user could tamper the API server's response. Now namespaces are sanitized in fetchNamespaceTenancyMetrics.

- Around line 815-816: Update the polling setup around updateMetrics to prevent
overlapping batches: replace the fixed setInterval scheduling with
completion-driven scheduling that starts the next poll only after the current
updateMetrics work finishes. Preserve the existing initial poll and 30-second
delay while ensuring older in-flight responses cannot overlap newer metric
batches.

Fix included in release 5.1.0-0.nightly-2026-08-20-215013 |
Analysis / Root cause:
The Projects list page (Home > Projects) gated metrics column visibility on
CAN_GET_NS, a cluster-scoped namespace GET permission that non-admin users lack. Additionally,fetchNamespaceMetrics()used the cluster-scoped Prometheus endpoint (/api/prometheus), which returns 403 for non-admin users. As a result, non-admin users either saw no CPU/Memory columns at all, or saw hyphens for all projects.Solution description:
canGetNSgate fromshowMetrics)fetchNamespaceTenancyMetrics()that queries the per-namespace Prometheus tenancy endpoint (/api/prometheus-tenancy) for non-admin users, following the same pattern used byfetchOverviewMetricsinmetricUtils.tsand the pod list pagecanGetNS === true) continue using the efficient single cluster-wide query viafetchNamespaceMetrics()Screenshots / screen recording:
