A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

Unaudited dollar value2 of 3 inputs carry a receipt
Exposure$32,700over the next 30 days, if this record is yours
Movementno material movementthe record holds only daily drift and scoring model releases
Basisassumeda published average, not your estate

$32,700 = $4.99M incident cost x 1 exposure x 0.00655 likelihood

udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

What it is stated by the CNA

A cleartext transmission of sensitive information vulnerability in Palo Alto Networks PAN-OS Panorama that discloses an authenticated PAN-OS administrator's PAN-OS session cookie. When an administrator issues a context switch request into a managed firewall with an affected PAN-OS Panorama version, their PAN-OS session cookie is transmitted over cleartext to the firewall. An attacker with the ability to intercept this network traffic between the firewall and Panorama can access the administrator's account and further manipulate devices managed by Panorama. receipt
