OpenShift Must Gather Operator Improper Input Validation vulnerability

Description

A flaw was found in the MustGather.managed.openshift.io Custom Defined Resource (CRD) of OpenShift Dedicated. A non-privileged user on the cluster can create a MustGather object with a specially crafted file and set the most privileged service account to run the job. This can allow a standard developer user to escalate their privileges to a cluster administrator and pivot to the AWS environment.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
