Is this vulnerability remotely exploitable?

The vulnerability is primarily exploited via malicious files rather than direct network access. An attacker typically needs to convince a user to open a crafted Flow or App package in PowerDocu. Distribution can happen over email, shared drives, or repositories, but execution occurs locally when the application processes the file.

What level of access does an attacker need?

An attacker only needs the ability to deliver a malicious package to a user of a vulnerable PowerDocu installation. They do not need prior access to the victim's system; user interaction (opening the file) is the main requirement.

What is the safest general fix pattern?

The safest approach is to disable unsafe polymorphic deserialization entirely for untrusted JSON input and parse packages into explicit, strongly-typed data models. Where polymorphism is unavoidable, restrict it to a vetted whitelist of benign types and enforce strict validation of JSON content before object construction.
