CVE-2026-9789: Acer Nitrorsense v3

High severity, CVSS 8.5. EPSS: 0.1% chance of exploitation in the next 30 days.

A Local Privilege Escalation (LPE) vulnerability affects Acer NitroSense software versions prior to 3.01.3052. The vulnerability stems from the the PSAdminAgent service, which creates a Named Pipe with a weak Access Control List (ACL). This allows any authenticated local user to connect and send commands. Because the service does not check the caller's privileges before running file deletion commands, a low-privileged local user can exploit this to delete arbitrary files with system authority.

Affected products

• Acer Nitrorsense v3: from 3.01.3001, up to and including 3.01.3052
