When configured with system password authentication, a user existence oracle may exist in certain build configurations. An attacker could distinguish existing from non-existing usernames by observing authentication failure behavior. Impact is limited to username enumeration and requires non-default compile options or uncommon password file states; default BusyBox builds with shadow password support are not affected.","state":0,"publishedAt":"2026-10-13T16:58:04.572+00:00","modifiedAt":"2026-10-13T17:16:43.731+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"busybox","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Hardened Images\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"busybox\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/a:redhat:hummingbird:1\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://access.redhat.com/security/cve/CVE-2026-88834","https://bugzilla.redhat.com/show_bug.cgi?id=2531348"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88834","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88834","identifiers":["CVE-2026-88834"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
