CyberRota Analysis
AI-GeneratedVersions of MCP Appium prior to 1.85.10 are vulnerable to an injection flaw in the createLocatorGeneratorUI function, allowing attackers to inject arbitrary HTML and JavaScript into the MCP UI. This can lead to unauthorized execution of MCP tools, enabling actions such as taking screenshots or accessing sensitive data. Organizations using affected versions for mobile app testing should prioritize updating to the patched version to mitigate potential exploitation risks.

Original NVD Description
MCP Appium is an MCP server that provides AI assistants with tools to automate mobile app testing on Android and iOS. In versions prior to 1.85.10, the createLocatorGeneratorUI function interpolates attacker-controlled element attributes — text, content-desc, resource-id, and locator selector values — directly into an HTML template literal without any HTML or JavaScript context escaping. An attacker who controls the UI of the app under test can inject arbitrary HTML and JavaScript into the MCP UI resource returned by the generate_locators tool. When a victim's MCP client renders this resource, the injected script executes and can invoke arbitrary MCP tools via window.parent.postMessage, leading to unauthorized MCP tool execution such as taking screenshots, reading page source, or any other registered capability. This issue has been fixed in version 1.85.10.
