Prioritization signals

• CVSS 9.8 (critical)
• Active exploitation in the wild (per Defused)
• Business-critical financial application as the target

Defensive recommendations

• Restrict reachability of EBS components from untrusted networks, especially internet-exposed instances.
• Inspect EBS and application logs for signs of exploitation and unusual access.
• Apply compensating controls (access restriction, monitoring) until patched and treat exposed instances as potentially at risk.
