CVE-2026-43910

Full vulnerability record from the local CVENow database.

Description

Appium Java Client is the Java language binding for writing Appium tests that conform to the W3C WebDriver protocol. From 8.2.1 until 10.1.1, when directConnect(true) is enabled, AppiumCommandExecutor.setDirectConnect() reads the directConnectHost, directConnectPort, and directConnectPath fields from the server's NEW_SESSION response and rebuilds the client's server URL from them, validating only that the protocol is https, with no host allowlist or IP validation; a rogue or compromised server can therefore redirect all subsequent session traffic to an arbitrary destination, enabling full interception of session traffic and a server-side request forgery pivot to internal hosts, including cloud metadata (IMDS) credential theft. This vulnerability is fixed in 10.1.1.

Desde la 8.2.1 hasta la 10.1.1, cuando directConnect(true) está habilitado, AppiumCommandExecutor.setDirectConnect() lee los campos directConnectHost, directConnectPort y directConnectPath de la respuesta NEW_SESSION del servidor y reconstruye la URL del servidor del cliente a partir de ellos, validando solo que el protocolo es HTTPS, sin una lista de permitidos de host o validación de IP; un servidor malicioso o comprometido puede, por lo tanto, redirigir todo el tráfico de sesión subsiguiente a un destino arbitrario, lo que permite la intercepción completa del tráfico de sesión y una falsificación de petición del lado del servidor como pivote hacia hosts internos, incluyendo el robo de credenciales de metadatos de la nube (IMDS). Esta vulnerabilidad está corregida en la 10.1.1."
