Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1

2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker

3
Lateral reach — past segmentation narrative 3
Attacker
I extract disclosed information for further reconnaissance or targeted attacks.
Business
Compromised data becomes leverage for follow-on attacks, fraud, or competitive intelligence theft.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
