About Acer Nitrosense
CVE-2026-8069 affects Acer Nitrosense, a product from Acer. Before acting, confirm where Acer Nitrosense runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: PredatorSense version 3.00.3136 to 3.00.3196 contain Local Privilege Escalation (LPE) vulnerability.The program exposes a Windows Named Pipe that uses a custom protocol to invoke internal functions. However, this Named Pipe is misconfigured, allowing any authenticated local user to execute arbitrary code with NT AUTHORITY\SYSTEM privileges and to delete arbitrary files with SYSTEM privileges. By leveraging this, an attacker can execute arbitrary code on the target system with elevated privileges.
The weakness class is Path Traversal. An attacker can reach files outside the intended folder by tampering with a file path.
Based on its CVSS vector, the flaw needs local or adjacent access, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Acer Nitrosense and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Acer Nitrosense named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.
CTEM action plan
| CTEM stage | What to do for this CVE |
|---|---|
| Scope | Add every business service that depends on Acer Nitrosense to the current CTEM cycle. |
| Discover | Find all instances, including shadow and cloud deployments, and record versions and exposure. |
| Prioritize | Rank using EPSS and CVSS together with asset exposure and business impact. |
| Validate | Confirm the flaw is reachable and exploitable in your environment and that compensating controls work. |
| Mobilize | Assign the fix to the asset owner with a due date matched to the priority, then verify closure. |
