CVE-2026-71473 (GCVE-0-2026-71473)

Vulnerability from cvelistv5 – Published: 2026-08-12 21:40 – Updated: 2026-08-13 13:35

Title

Acm-search-v2-rhel9: search-v2-operator: addonfactory.getvaluesfromaddonannotation enables arbitrary helm-values override per spoke

Summary

A flaw was found in the `search-v2-operator` component. A user with specific administrative permissions on a managed cluster can exploit a vulnerability that allows them to inject arbitrary configuration data. This manipulation can override critical settings, leading to the replacement of container images. This ultimately results in container image injection on the managed cluster, potentially compromising its integrity.
