An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

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.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
