CVE-2026-50110: Stonefly Storage Concentrator

Critical severity, CVSS 9.2. EPSS: 0.2% chance of exploitation in the next 30 days.

Storage Concentrator (SC & SCVM) contains hardcoded credentials for numerous internal services embedded within a configuration file. While the credentials are stored in an encoded format, the encoding can be reversed to plaintext. The exposed credentials span a broad range of internal services, including database accounts, licensing, replication services, and third-party integrations, meaning successful exploitation of this vulnerability could provide an attacker with unauthorized access to multiple interconnected systems.

Affected products

• Stonefly Storage Concentrator: before 8.0.4.26 (fixed in 8.0.4.26)
• Stonefly Storage Concentrator Virtual Machine: before 8.0.4.26 (fixed in 8.0.4.26)
