Frequently Asked Questions
1
Who is realistically exposed to exploitation?
Affected PAPPL installations are exposed only after an attacker can execute low-privileged code on the target system. This is a local privilege-escalation issue, so it does not describe unauthenticated remote exploitation.
2
What access does an attacker need before exploiting the flaw?
The attacker must first obtain the ability to run low-privileged code on the affected system. Successful exploitation can then escalate those privileges.
