CVE-2026-71845
Description
A flaw was found in insights-client. The setDefault() function logs the value of every environment variable it processes, including CCX_TOKEN, a bearer credential used in disconnected cluster deployments. When glog verbosity is set to level 2 or higher, the token is written in clear text to the pod log on every startup. An attacker with access to pod logs or centralized logging could obtain the credential, leading to unauthorized access to the CCX API.
Statement
This is a Moderate flaw in Red Hat Advanced Cluster Management for Kubernetes. The insights-client component logs the CCX_TOKEN bearer credential in clear text at startup when glog verbosity is set to level 2 or higher. This credential is used by disconnected cluster deployments as an alternative to cloud.redhat.com. An attacker with access to pod logs or centralized logging could obtain the credential and use it to access the CCX API on behalf of the affected organization.
Mitigation
Ensure glog verbosity on the insights-client Deployment is set below level 2 (-v=0 or -v=1). If CCX_TOKEN must be configured for disconnected environments, restrict access to pod logs in the open-cluster-management namespace and to centralized logging backends.
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.

Confidentiality
Technical Impact: Read Application Data
Logging sensitive user data, full path names, or system information often provides attackers with an additional, less-protected path to acquiring the information.
