fix: the processutils in ProcessUtils.java

[anupamme]

Summary

Fix critical severity security issue in src/plugins/terminal/src/android/ProcessUtils.java.

Vulnerability

Field	Value
ID	V-001
Severity	CRITICAL
Scanner	multi_agent_ai
Rule	V-001
File	src/plugins/terminal/src/android/ProcessUtils.java:45
Assessment	Likely exploitable

Description: The ProcessUtils.killProcessTree() and killProcess() methods construct shell commands by concatenating the process ID (pid) directly into a command string passed to Runtime.getRuntime().exec(). The exec(String) method invokes a shell, allowing shell metacharacters in the pid to chain arbitrary commands if the pid value is influenced by user input or external data.

Evidence

Exploitation scenario: An attacker who can influence the pid parameter (e.g., through crafted process or process enumeration manipulation) can inject shell metacharacters.

Scanner confirmation: multi_agent_ai rule V-001 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.

Threat Model Context

This is a Node.js library - vulnerabilities affect downstream consumers who use this package.

Greptile Summary

Replaces string-based Runtime.exec calls with explicit argument arrays when terminating individual processes and process groups, preserving existing command semantics while avoiding command-string parsing.

Confidence Score: 5/5

The PR appears safe to merge with no identified functional or security regressions.

The changed array-based process execution produces the same arguments as the previous commands for numeric PIDs, while avoiding unsafe command-string construction.

Important Files Changed

Filename	Overview
src/plugins/terminal/src/android/ProcessUtils.java	Both process-kill paths now pass fixed command arguments separately; realistic callers provide numeric PIDs, so behavior remains equivalent without introducing a reachable regression.
