CVE-2026-8069 Overview
CVE-2026-8069 is a local privilege escalation (LPE) vulnerability affecting Acer PredatorSense versions 3.00.3136 through 3.00.3196. The flaw resides in a Windows Named Pipe that PredatorSense exposes to invoke internal functions through a custom protocol. The Named Pipe is misconfigured, granting any authenticated local user the ability to interact with privileged operations. Attackers can leverage this access to execute arbitrary code under NT AUTHORITY\SYSTEM and delete arbitrary files with SYSTEM privileges. The weakness is categorized under [CWE-22] (Path Traversal).
Critical Impact
Any authenticated local user can escalate to SYSTEM, achieving full control of the host and arbitrary file deletion.
Affected Products
- Acer PredatorSense 3.00.3136
- Acer PredatorSense versions between 3.00.3136 and 3.00.3196

Technical Details for CVE-2026-8069
Vulnerability Analysis
PredatorSense runs a privileged service that exposes a Windows Named Pipe for inter-process communication. The Named Pipe implements a custom protocol to dispatch internal functions, including file operations executed in the SYSTEM security context. Because the pipe's security descriptor allows access to any authenticated local user, the trust boundary between standard users and the privileged service collapses. An attacker connects to the pipe, sends crafted protocol messages, and instructs the service to perform actions on their behalf. The path traversal weakness ([CWE-22]) compounds the issue, allowing manipulation of file paths supplied through the pipe to reach files outside intended directories.
Root Cause
The root cause is the misconfigured access control list on the Named Pipe combined with insufficient validation of path arguments passed across the pipe interface. The service trusts client-supplied input and operates on files without verifying that the calling user holds the necessary privileges for the target resource.
Attack Vector
Exploitation requires local authenticated access. The attacker opens a handle to the PredatorSense Named Pipe, crafts a protocol message that invokes a privileged internal function, and supplies attacker-controlled parameters. The service executes the request as SYSTEM, enabling arbitrary code execution or arbitrary file deletion. No user interaction is required beyond the attacker's own session.
No public proof-of-concept code is available. Refer to the Acer Community Knowledge Base for vendor-supplied technical details.
Detection Methods for CVE-2026-8069
Indicators of Compromise
- Unexpected child processes of PredatorSense service binaries running as NT AUTHORITY\SYSTEM
- Non-administrative user sessions opening handles to the PredatorSense Named Pipe
- Unexplained deletion of files in protected directories such as C:\Windows\System32 or C:\Program Files
Detection Strategies
- Monitor Named Pipe creation and connection events (Sysmon Event IDs 17 and 18) targeting PredatorSense pipes from non-SYSTEM accounts
- Alert on process creation events where the parent is a PredatorSense service and the child is a shell, scripting host, or LOLBin
- Correlate standard-user logons with subsequent SYSTEM-context file operations on the same host
Monitoring Recommendations
- Inventory endpoints running PredatorSense versions 3.00.3136 through 3.00.3196 using software asset management telemetry
- Audit file deletion events in sensitive directories and tie them to the initiating process and token
- Track installation and update events for PredatorSense to confirm patch deployment status
How to Mitigate CVE-2026-8069
Immediate Actions Required
- Identify all systems running affected PredatorSense versions and prioritize them for remediation
- Restrict local logon rights on affected hosts to reduce the population of users who can exploit the pipe
- Stop or disable the PredatorSense service on systems where the application is not required
Patch Information
Consult the Acer Community Knowledge Base for the vendor's official remediation guidance and updated PredatorSense release. Upgrade to a fixed version above 3.00.3196 once it is published by Acer.
Workarounds
- Uninstall PredatorSense on systems where the utility is not actively used
- Disable the PredatorSense service via services.msc to prevent the vulnerable Named Pipe from being created
- Apply application allowlisting to block unauthorized processes from interacting with the PredatorSense pipe
# Configuration example: disable the vulnerable service
sc.exe stop PredatorSenseService
sc.exe config PredatorSenseService start= disabled
