CVE-2026-71845 Red Hat CVE debrief

Who should care

Red Hat users and administrators utilizing insights-client, especially those with disconnected cluster deployments, should be aware of this vulnerability and take steps to mitigate the risk of credential exposure. This includes reviewing logging configurations, implementing centralized logging and access controls, and rotating CCX_TOKEN credentials for all affected systems. Security teams and operators responsible for managing insights-client deployments should prioritize this vulnerability based on its potential impact on system security and data integrity.

Technical summary

The insights-client's setDefault() function logs environment variables, including the CCX_TOKEN bearer credential used in disconnected cluster deployments, in clear text to pod logs when glog verbosity is set to level 2 or higher. This allows an attacker with access to pod logs or centralized logging to obtain the credential, potentially leading to unauthorized access to the CCX API. Affected systems require review of logging configurations and potential updates to prevent credential exposure.

Defensive priority

Medium-severity vulnerability in Red Hat's insights-client, allowing potential unauthorized access to the CCX API through exposed bearer credentials in pod logs.

Recommended defensive actions

• Review and adjust logging verbosity for insights-client to prevent clear text credential exposure
• Implement centralized logging and access controls to protect pod logs
• Rotate and update CCX_TOKEN credentials for all affected systems
• Monitor for suspicious activity related to CCX API access
• Apply vendor-provided patches or updates for insights-client

Evidence notes

The setDefault() function in insights-client logs environment variables, including the CCX_TOKEN bearer credential, in clear text to pod logs at verbosity level 2 or higher. An attacker with access to pod logs could obtain the credential. This issue affects Red Hat's insights-client, particularly in disconnected cluster deployments. Verify logging configurations and consider implementing centralized logging and access controls.
