An attacker can use a specially crafted webpage to force a rendertron headless chrome process to render internal sites it has access to, and display it as a screenshot. Suggested mitigations are to upgrade your rendertron to version 3.0.0, or, if you cannot update, to secure the infrastructure to limit the headless chrome's access to your internal domain.","published":"2021-02-23T12:15:12.600Z","modified":"2026-08-14T09:05:39.496829Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"rendertron","fixedVersion":"3.0.0"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/GoogleChrome/rendertron/releases/tag/3.0.0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T09:05:39.496829Z"}}
