**Avast Sandbox 0‑Day PoC Report:** Researcher Chaotic Eclipse (MSNightmare) published a public proof-of-concept claiming a local privilege‑escalation zero‑day in Avast Antivirus Sandbox that can dump the Windows SAM and spawn a SYSTEM shell on fully patched Windows 11 systems; the repository is publicly accessible, increasing risk, but the claim remains unverified by GenDigital and has no CVE or coordinated vendor response at time of writing.
