CVE-2026-22550Network attack vector

Authenticated arbitrary OS command execution

Published Feb 3, 2026 · Updated Feb 3, 2026

OS command injection in ELECOM WRC-X1500GS-B and WRC-X1500GSA-B 1.12 and earlier allows remote authenticated users to execute commands. ELECOM and JPCERT/CC have not disclosed the affected request handler, parameter, or command-construction operation. A valid high-privilege management login and network access to the router interface are required; successful exploitation grants arbitrary OS command execution on the device.
