CVE-2026-55721Network attack vector

Sensitive data disclosure via cookie SQL injection

Published Jun 30, 2026 · Updated Jun 30, 2026

SQL injection in StoneFly Storage Concentrator and SCVM before 8.0.4.22 allows remote attackers to read sensitive database data. The login.pl and debug.pl scripts place attacker-controlled cookie values directly into database queries without adequate neutralization. No authentication or user interaction is required, and crafted cookies expose session tokens, password hashes, and stored secret keys.
