Recommended defensive actions

• Verify GPAC 26.08-DEV installations for exposure
• Assess feasibility of upgrading to abi-16.24
• Monitor for local exploitation attempts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
