SmartFabric OS10 Software: Download of Code Without Integrity Check
CVE-2026-63696 is a critical-severity download of code without integrity check vulnerability in SmartFabric OS10 Software from Dell, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 10.6.1.3 as the first without the flaw, so updating SmartFabric OS10 Software to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update SmartFabric OS10 Software to 10.6.1.3 or a later version.

Official description
Dell SmartFabric OS10 Software, versions prior to 10.6.1.3, contains a Download of Code Without Integrity Check vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Code execution.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Download of Code Without Integrity Check
The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.
How developers prevent this class of flaw
- Perform proper forward and reverse DNS lookups to detect DNS spoofing.
- Encrypt the code with a reliable encryption scheme before transmitting.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
