CVE-2026-80239 · Severity: low · CVSS 2.4 · Published 2026-09-09

Dell Secure Connect Gateway is a network security appliance used to manage secure remote access and connections. Versions prior to 5.36.00.16 (appliance) and 5.36.00.00 (application) leave sensitive system information exposed through uncleared debug output. An attacker with physical access to the device could potentially retrieve this debug information, compromising operational security and potentially exposing credentials or system configuration details.
