CVE-2025-0052Network attack vector

Unauthenticated denial of service via invalid authentication input

Published Jun 10, 2025 · Updated Jun 11, 2025

Improper input validation in Pure Storage FlashBlade allows remote attackers to interrupt the system via crafted authentication input. The authentication component processes invalid input without adequate validation, but Pure Storage has not disclosed the specific field or failing operation. No authentication or user interaction is required; successful exploitation can interrupt file and object storage service.
