A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.","published":"2026-10-16T00:17:05.573","modified":"2026-10-16T00:17:05.573","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-84823"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527902"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-16T00:17:05.573"}}
