A flaw has been found in jiantao88 android-mcp-server up to cfb872b2446794193b58edd63f4dbf6af48a6292. The impacted element is the function child_process.exec of the file build/index.js of the component Command Execution. Executing a manipulation of the argument deviceId/packageName/permission/extras[].key/extras[].value can lead to os command injection. It is possible to launch the attack on the local host. The exploit has been published and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. This patch is called 14e2bf27c88ba137e35cbb0c2a75f72b595bb98a. It is advisable to implement a patch to correct this issue.
