CVE-2026-9789
A Local Privilege Escalation (LPE) vulnerability affects Acer NitroSense software versions prior to 3.01.3052.
Overview
CVE-2026-9789 is a known-severity vulnerability. It was published on May 28, 2026.
Technical description
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.
