CVE-2025-0051Network attack vector

Unauthenticated service interruption via malformed authentication input

Published Jun 10, 2025 · Updated Jun 11, 2025

Improper input validation in Pure Storage FlashArray Purity allows remote attackers to interrupt service during authentication. Pure Storage has not published the authentication field, parser, or validation operation that mishandles the input. No credentials or user interaction are required; successful exploitation interrupts array service without reported data access or modification.
