Dell disclosed two high-severity vulnerabilities in PowerProtect Data Domain appliances running multiple DD OS releases, including a weak-credentials flaw tracked as CVE-2026-23853 and a missing-authentication issue tracked as CVE-2026-26944. The weak-credentials vulnerability affects Feature Release versions 7.7.1.0 through 8.5, LTS2025 8.3.1.0 through 8.3.1.20, and LTS2024 7.13.1.0 through 7.13.1.50, and could allow an unauthenticated attacker with local access to gain unauthorized access to the system. The issue is classified as CWE-1391 and carries a CVSS v3.1 score vector of AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.
Dell also reported CVE-2026-26944, a missing authentication for critical function flaw classified as CWE-306, which could allow an unauthenticated remote attacker to execute arbitrary commands with root privileges if an authenticated user performs a specific action. That vulnerability is rated with the CVSS v3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. Both issues were referenced in Dell security guidance, including advisory DSA-2026-060, and affect backup infrastructure that may be critical to recovery operations, making remediation and version review a priority for defenders.

Dell disclosed multiple high-severity vulnerabilities affecting enterprise storage and backup platforms, including **PowerProtect Data Domain**, **Storage Manager**, and **Unity**. In PowerProtect Data Domain, **CVE-2026-26944** allows unauthenticated remote attackers to reach a privileged function and potentially execute commands as `root` if a legitimate user performs a specific action, while **CVE-2026-26943** and **CVE-2026-23778** enable root-level command execution for attackers with high privileges. Dell said the issues affect several DD OS release tracks, Data Domain Virtual Edition, APEX Protection Storage, Data Domain Management Center, and PowerProtect DP Series appliances, and released fixes through advisory **DSA-2026-060**, adding that it had no indication of active exploitation. Dell also issued critical updates for other storage lines. **Dell Storage Manager** vulnerabilities **CVE-2025-43994** and **CVE-2025-43995** expose management functions and APIs to unauthenticated remote access or authentication bypass, potentially affecting all storage arrays managed by a vulnerable instance; Dell’s advisory **DSA-2025-393** recommends upgrading to **2020 R1.22** or later. In **Dell Unity**, **CVE-2025-36604** permits unauthenticated remote OS command injection, while **CVE-2025-36606** and **CVE-2025-36607** allow authenticated attackers to escape restricted utilities and run commands as `root`; Dell remediated those flaws in **Unity OE 5.5.1** and later. The disclosures highlight elevated risk to backup integrity, storage administration, and ransomware recovery operations if exposed management interfaces remain unpatched.

dCERT issued multiple advisories for **Dell PowerProtect Data Domain OS** and **PowerDNS**, highlighting newly tracked security flaws across both products. For Dell backup appliances, advisory `2026-1097` reported multiple vulnerabilities in PowerProtect Data Domain OS, followed by advisory `2026-1218`, which specifically warned that a vulnerability in the platform could allow **code execution**. dCERT also published two separate advisories on **PowerDNS**—`2026-1204` and `2026-1215`—each describing multiple vulnerabilities affecting the DNS software. The notices indicate a concentrated wave of disclosures affecting enterprise backup infrastructure and DNS services, with the Dell issue standing out because of its potential to let attackers execute code on vulnerable systems.

Dell released multiple security advisories covering vulnerabilities across a broad set of enterprise infrastructure products, and the Canadian Centre for Cyber Security urged organizations to review the notices and apply updates. The affected technologies span storage, networking, data protection, and server platforms, including **Connectrix Switches and Directors**, **AMD-based PowerEdge Servers**, **Dell Command | Update** versions prior to `5.7.0`, **PowerProtect Data Domain**, and **Dell Storage Manager - Replay Manager for Microsoft Servers** versions prior to `8.0.3`. Additional advisories also affected **Data Protection Advisor**, **Dell EMC Isilon OneFS**, **Dell EMC PowerScale**, **Dell Networking OS10**, **PowerProtect DP Series Appliance**, **Elastic Cloud Storage**, **ObjectScale**, and several **PowerSwitch** models. The Canadian notice linked Dell advisories including `DSA-2026-041`, `DSA-2026-171`, `DSA-2026-058`, and `DSA-2026-190`, and characterized the activity as a vendor patch and mitigation effort rather than evidence of active exploitation.
