ThinOS 10: Improper Neutralization of Special Elements used in a Command
CVE-2026-81048 is a high-severity improper neutralization of special elements used in a command vulnerability in ThinOS 10 from Dell, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 2605_10.2616 as the first without the flaw, so updating ThinOS 10 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.35% chance of exploitation within 30 days, higher than 84% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update ThinOS 10 to 2605_10.2616 or a later version.
- Update Thinos to 2605_10.2616 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.

Official description
Dell ThinOS 10, versions prior to 2605_10.2616, contain an Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Remote Code execution
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
