CVE-2026-49188
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe ai_cmd utility executes with full root permissions. It pipes socket inputs directly to popen(), paving the way for unauthenticated users to execute arbitrary root commands.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe ai_cmd utility runs with root privileges and accepts socket input that is directly piped to the popen() function without sanitization. This allows any unauthenticated remote attacker to inject and execute arbitrary shell commands with full root privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck if the target device is an Acer Connect M6e 5g router/gateway. This may be visible in device documentation, web interface, or by checking the device label/ casing.Affected if The device is not an Acer Connect M6e 5g, the vulnerability does not apply.
-
Check firmware versionAccess the device web interface or CLI and retrieve the firmware version. Look for a version string starting with 'm6e_ai_' (for example, in system info or firmware update settings). Compare the version to 'm6e_ai_1.00.000019'.Affected if Firmware version is m6e_ai_1.00.000019 or lower.
-
Locate the ai_cmd binaryOn the device file system, search for a binary named 'ai_cmd' (common paths may include /usr/bin/, /sbin/, or custom application directories). Use 'find / -name ai_cmd 2>/dev/null' via shell access if available.Affected if The ai_cmd binary does not exist on the device, the vulnerability does not apply.
-
Verify ai_cmd runs as rootCheck the file permissions and ownership of the ai_cmd binary. Use 'ls -la /path/to/ai_cmd' to view ownership. If the binary is owned by root and has the setuid bit or runs as a root-owned service, it operates with root privileges.Affected if ai_cmd does not execute with root privileges, the privilege escalation aspect of this CVE does not apply.
-
Check socket/service exposureDetermine if ai_cmd listens on a network socket or is exposed via a service. Check running processes ('ps') for ai_cmd, and review network listeners ('netstat' or 'ss') for ports associated with this utility.Affected if ai_cmd is not network-accessible or not running as a service, remote exploitation is not possible.
The environment is affected if the device is an Acer Connect M6e 5g with firmware version m6e_ai_1.00.000019 or lower, and the ai_cmd utility exists, runs as root, and is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement authentication on the socket interface and sanitize all user input before passing to popen(), or replace popen() with safer execution methods that do not invoke shell interpretation.
