{"id":"CVE-2026-58191","aliases":["GHSA-3wgp-x9p5-c7cc"],"url":"https://o3.security/vulnerability/CVE-2026-58191","summary":"Appium: Reflected XSS / arbitrary JS in @appium/base-driver /test/guinea-pig* routes","details":"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.","published":"2026-07-08T20:57:43.237Z","modified":"2026-08-12T03:51:20.721779714Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"},"epss":{"score":0.0022,"percentile":0.12643,"asOf":"2026-07-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@appium/base-driver","fixedVersion":"10.7.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58191.json"},{"type":"ADVISORY","url":"https://github.com/appium/appium/security/advisories/GHSA-3wgp-x9p5-c7cc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58191"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.721779714Z"}}
