OpenFeature Operator vulnerable to Cluster-level Privilege Escalation

Description

Impact

On a node controlled by an attacker or malicious user, the lax permissions configured on open-feature-operator-controller-manager can be used to further escalate the privileges of any service account in the cluster.

The increased privileges could be used to modify cluster state, leading to DoS, or read sensitive data, including secrets.

Patches

The patch mitigates this issue by restricting the resources the open-feature-operator-controller-manager can modify.

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.
