CVE-2026-22271
Published: 23 January 2026
Summary
CVE-2026-22271 is a high-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Dell Elastic Cloud Storage. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 7.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-13 (Cryptographic Protection) and SC-8 (Transmission Confidentiality and Integrity).
Deeper analysis
CVE-2026-22271 is a Cleartext Transmission of Sensitive Information vulnerability (CWE-319) present in Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.2.0.0. Published on 2026-01-23, the issue has a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high potential impact despite elevated complexity and user interaction requirements.
An unauthenticated attacker with remote network access could potentially exploit this vulnerability, leading to information exposure. Exploitation requires high attack complexity and user interaction, such as tricking a user into performing an action, but successful attacks could result in high confidentiality, integrity, and availability impacts within the unchanged scope.
