IBM disclosed CVE-2026-12628, a high-severity authentication bypass vulnerability in IBM Storage Protect Client and IBM Storage Protect Snapshot for Windows versions 8.1.0.0 through 8.2.1.0. The flaw is caused by a hardcoded credential in the FlashCopy Manager authentication mechanism and improper validation of authentication responses, allowing an unauthenticated remote attacker to establish a trusted session.
Successful exploitation could let an attacker impersonate legitimate clients and gain unauthorized access to protected services and system resources. The issue is rated CVSS 3.1 8.1 (High) and is described as remotely exploitable. IBM recommends updating affected components and correcting the authentication design by removing hardcoded credentials and enforcing proper validation of authentication responses.
