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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2},"cwes":["CWE-441","CWE-918"],"references":["https://github.com/appium/java-client/commit/2b9cd442b9dbf56ccc6f1e83aeeb411c0ec230c9","https://github.com/appium/java-client/pull/2408","https://github.com/appium/java-client/releases/tag/v10.1.1","https://github.com/appium/java-client/security/advisories/GHSA-28f5-38xr-jh2w","https://github.com/appium/java-client/security/advisories/GHSA-28f5-38xr-jh2w"],"products":["appium:java-client"],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-43910","score":0.0043,"percentile":0.36921,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-28f5-38xr-jh2w","url":"https://osv.dev/vulnerability/GHSA-28f5-38xr-jh2w","summary":"java-client Allows Network Pivot via Unvalidated directConnect Redirect in AppiumCommandExecutor","modified":"2026-07-28T14:41:49.871148Z","packages":[{"ecosystem":"Maven","name":"io.appium:java-client","purl":"pkg:maven/io.appium/java-client","ranges":[">=8.2.1 <10.1.1"],"fixed":["10.1.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
