How to fix CVE-2025-70042?

Within 24 hours: Identify all ThermaKube master instances in your environment and document their network position; implement network segmentation to restrict outbound connections from affected systems to internal resources only. Within 7 days: Deploy WAF rules to block suspicious request patterns targeting internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and implement request input validation; disable any non-essential ThermaKube features that accept external URLs or proxying capabilities. Within 30 days: Evaluate emergency patching timelines from oslabs-beta; develop a migration plan to alternative solutions if patch availability remains uncertain; conduct a forensic audit of ThermaKube logs for signs of exploitation.
