Root access gives an attacker or administrator complete control of a Unix-like system, allowing changes to data, software, accounts, and security settings.

Background for this topic.
Root access is unrestricted administrative control of a Unix or Linux system. The root account, or an equivalent privilege obtained through mechanisms such as sudo, can read or change nearly any file, alter system configuration, install software, and control running processes. Related uses of “root” may describe equivalent administrator privileges in containers, cloud workloads, network appliances, or mobile devices.
Because root privileges can bypass ordinary access controls, stolen administrative credentials or a vulnerability that enables privilege escalation can let an attacker modify security settings, access protected data, establish persistence, or disrupt the host. Organizations generally reduce exposure by disabling direct root login where practical, using named administrator accounts with least privilege, protecting privileged authentication with strong controls, and recording and reviewing elevation events. Vulnerability management should prioritize flaws that can grant local or remote root-level execution; during an incident, investigators must assess whether root access was obtained and treat the host’s integrity as potentially compromised.

Pull the certificate off the flash of a Shark RV2320EDUS robot vacuum, and you can run root commands on other people's Shark vacuums across the same AWS region: watch the camera, drive the robot, read the map of the house, and take the Wi-Fi password in plaintext
Open a repository in Cursor on Windows and, if a file named git.exe is sitting in the project root, Cursor runs it. No click, no approval dialog, no warning that anything in the folder is about to execute
Researchers at Nebula Security have disclosed GhostLock (CVE-2026-43499), a 15-year-old Linux kernel flaw that lets any logged-in user take full root control of a machine that has not been patched
