Use of Hard-coded Credentials vulnerability in Mitsubishi Electric Room Air Conditioners (for Japan and outside Japan); Wireless LAN Adapters for Room Air Conditioners (for Japan and outside Japan); Wireless LAN Adapters for Packaged Air Conditioners (for Japan and outside Japan); Refrigerators (for Japan); Heat Pump Water Heaters / HEMS-Compatible Adapters / Wireless LAN Adapters (for Japan); Bathroom Dryer / Heater / Ventilation Systems (for Japan); Adapters for Airflow Ventilation Systems, Heat Pump Chilled / Hot Water Systems, and Ventilation / Air-Conditioning System Air Resorts (for Japan); Lossnay Central Ventilation Systems (for Japan); Smart Switches for Ventilation Fans and Lossnay (for Japan); IH Cooking Heaters (for Japan); and Rice Cookers (for Japan) allows an attacker within Wi-Fi radio range of an affected product to access the affected product using a hard-coded SSID and password, thereby obtaining device data such as operation status, room set temperature, and room temperature; changing the air-conditioner or Wi-Fi settings; or causing Wi-Fi communication to enter a denial-of-service (DoS) condition.
CVE-2026-5667
This high-severity CVE scores 7.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 95% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
