Answer in brief
CVE-2026-19983 records a Unknown severity vulnerability in GL.iNet XE3000 NAS Command Service gl_nas_sys os command injection. The current sources do not mark it as known exploited. The current feed maps GL.iNet/A1300 (generic), GL.iNet/AX1800 (generic), GL.iNet/AXT1800 (generic), GL.iNet/MT2500 (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
