CVE-2026-70495
Description
A flaw was found in search-v2-operator. This component's search-serviceaccount has overly broad permissions, allowing it to impersonate users and groups across the entire cluster. If an attacker gains access to any of the pods running under this service account, they could exploit this to achieve system:masters access, granting them full control over the cluster.
Statement
Critical: This flaw in search-v2-operator allows an attacker who gains a foothold in any of the four pods running under the search-serviceaccount to achieve cluster-wide system:masters privileges. This escalation of privilege poses a severe risk to the integrity and control of the Red Hat Advanced Cluster Management for Kubernetes environment.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
