A code injection vulnerability has been identified in BUFFALO Wi-Fi router products. Successful exploitation of this flaw could lead to arbitrary code execution on the affected devices, granting attackers significant control over the router and potentially the connected network. The vulnerability affects routers with firmware versions ≤See "References" section. A fix is expected to be released by BUFFALO.
The impact of this code injection vulnerability is severe. An attacker who successfully exploits it can execute arbitrary code on the router, effectively gaining complete control. This could involve modifying router configurations, intercepting network traffic, installing malware, or using the router as a launchpad for attacks against other devices on the network. The blast radius extends to all devices connected to the compromised router, making it a critical security risk. The ability to execute arbitrary code bypasses standard security measures and allows for a wide range of malicious activities.
This vulnerability was publicly disclosed on 2026-03-27. The CVSS score of 8.8 (HIGH) indicates a significant risk. Public proof-of-concept exploits are not currently known, but the potential for remote code execution makes this a high-priority vulnerability. Monitor CISA and BUFFALO advisories for updates and potential exploitation activity.

The primary mitigation for CVE-2026-32669 is to upgrade to a patched firmware version as soon as it becomes available from BUFFALO. Until a patch is released, consider implementing temporary workarounds such as restricting access to the router's management interface from untrusted networks. Monitor network traffic for any unusual activity that might indicate an attempted exploit. Consider enabling router firewall rules to limit inbound connections to essential services only. After upgrading, verify the firmware version to confirm the patch has been successfully applied.
Update your BUFFALO Wi-Fi router firmware to the latest version provided by the manufacturer. Refer to the BUFFALO INC. website for the latest updates and installation instructions. This will resolve the code injection vulnerability.
