CVE-2026-58191: Appium Appium/base-Driver

Medium severity, CVSS 6.1. EPSS: 0.6% chance of exploitation in the next 30 days.

Appium is a cross-platform automation framework for all kinds of apps, built on top of the W3C WebDriver protocol. Prior to 10.7.0, Appium's base-driver unconditionally mounts the /test/guinea-pig, /test/guinea-pig-scrollable, and /test/guinea-pig-app-banner routes, and compileLodashTemplate reflects the throwError query parameter, comments POST field, and User-Agent request header into HTML without escaping, allowing reflected cross-site scripting and arbitrary JavaScript execution on the server origin. This issue is fixed in version 10.7.0.

Affected products

• Appium Appium/base-Driver: before 10.7.0 (fixed in 10.7.0)
