CVE-2026-80172: Dell Secure Connect Gateway

Critical severity, CVSS 9.8. EPSS: 0.3% chance of exploitation in the next 30 days.

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Insufficient Verification of Data Authenticity vulnerability. An unauthenticated attacker with remote access could exploit this, leading to unauthorized access. This vulnerability is considered critical as an unauthenticated attacker can repeatedly reuse a captured request to generate ADMIN access and refresh tokens. Since there is no nonce validation or time limit on requests, the attack can be performed indefinitely. Dell recommends customers to upgrade at the earliest opportunity

Affected products

• Dell Secure Connect Gateway: before 5.36.00.00 (fixed in 5.36.00.00); before 5.36.00.16 (fixed in 5.36.00.16)
