CVE-2026-49188
CWE-489Published: June 4, 2026· Updated: Jun 17, 2026
Official Description
The 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.
Risk Analysis
This critical vulnerability allows unauthenticated users to execute arbitrary root commands due to the ai_cmd utility executing with full root permissions and piping socket inputs directly to popen(). With a CVSS score of 9.8, this flaw presents a severe risk to confidentiality, integrity, and availability, requiring immediate action.
No public exploit is known for this vulnerability, and it is not listed in CISA's Known Exploited Vulnerabilities catalog. The flaw is remotely exploitable due to its network attack vector and low attack complexity.
To mitigate this, restrict the ai_cmd utility's permissions and sanitize all socket inputs before processing. Apply any available firmware updates for Acer Connect M6E 5G devices. Generic hardening includes implementing least privilege principles and input validation.
Technical Analysis
CVE-2026-49188 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
