What happened

The Primakon Pi Portal 1.0.18 API /api/V2/pp_udfv_admin endpoint, fails to perform necessary server-side validation. The administrative LoginAs or user impersonation feature is vulnerable to a access control failure. This flaw allows any authenticated low-privileged user to execute a direct PATCH request, enabling them to impersonate any other arbitrary user, including application Administrators.

This is due to a Broken Function Level Authorization failure (the function doesn't check the caller's privilege) compounded by an Insecure Design that permits a session switch without requiring the target user's password or an administrative token and only needs email of user.

About this data

This record was ingested from a data source. Retrieved: Nov 5, 2026, 00:26 UTC. Ingestion is not an independent editorial investigation.

NVD status: Analyzed. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
