No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

In multiple functions of LocalImageResolver.java, there is a possible Remote Persistent Denial of Service due to a DNG image rendering check bypass. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
