CVE-2026-58500: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in appium appium-mcpCVE-2026-58500 0 CVE-2026-58500 is a high-severity cross-site scripting (XSS) vulnerability in appium-mcp versions prior to 1.85.10. The vulnerability arises because the createLocatorGeneratorUI function directly interpolates attacker-controlled element attributes into an HTML template without proper escaping. This allows an attacker controlling the UI of the app under test to inject arbitrary HTML and JavaScript into the MCP UI resource. When rendered by a victim's MCP client, the injected script can execute arbitrary MCP tools via window.parent.postMessage, potentially leading to unauthorized actions such as taking screenshots or reading page source. The issue is fixed in version 1.85.10. Join the discussion | CVE Database V5 | 07/13/2026, 21:17:29 UTC Added: 07/13/2026, 21:18:19 UTC |
