Impact	Maximum risk (CVSS 10.0, EPSS 12.8%). AEM is used by major enterprises for web content management. Unauthenticated RCE with changed scope means the attacker can compromise not just AEM but connected systems.
Exploit ScenarioDerived	An attacker sends crafted requests to an AEM instance, exploiting the misconfiguration for code execution. The changed scope allows pivoting to connected content delivery networks, databases, and integrated marketing platforms.
