CVE-2026-3841: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in TP-Link Systems Inc. TL-MR6400 v5.3CVE-2026-3841 0 CVE-2026-3841 is a high-severity OS command injection vulnerability in the Telnet CLI of TP-Link TL-MR6400 v5.3 routers. It arises from improper sanitization of input data during certain CLI operations, allowing an authenticated attacker with elevated privileges to execute arbitrary system commands. Exploitation can lead to full device compromise, affecting confidentiality, integrity, and availability. No user interaction is required, but elevated privileges and network access via Telnet are necessary. Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to the critical nature of the device and its role in network infrastructure. Organizations using this router model should prioritize patching or mitigating this issue. Countries with widespread use of TP-Link networking equipment and strategic reliance on such devices are at higher risk.
