Technical Analysis

CVE-2026-102294 is an authenticated OS command injection vulnerability in TP-Link TL-WR841N v14. The flaw arises from improper neutralization of special elements in the IPv6 Gateway configuration input, which is incorporated into system commands without adequate sanitization. An authenticated administrator can supply crafted input to execute arbitrary OS commands on the device.

Potential Impact

Successful exploitation allows an authenticated administrator to execute arbitrary OS commands, potentially leading to unauthorized access to sensitive data, unauthorized modification of device configuration or services, and disruption of device operation.

Mitigation Recommendations

No patch or official remediation has been provided yet. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrative access to trusted users only and avoid using the vulnerable IPv6 WAN configuration features if possible.
