BlackFrost exploitation of CVE-2026-48217 in Northstar payment tier

window
12–18 Sep 2026

The recommended framing is a decision request, not a threat briefing: authorise the emergency change window for SecurePay remediation. The mitigation package costs $330K over four days and moves the modelled position from 87% / $214M to roughly 38% / $96M. Disclosure counsel should be engaged now, because the SEC 8-K materiality trigger attaches at 55% probability.
