{"schema":"threatline.record/2","record":{"id":"CVE-2026-88834","aliases":[],"summary":"Busybox: busybox: httpd user existence oracle in non-default shadow-disabled builds","details":"A flaw was found in BusyBox's httpd web server. 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.","categories":["Operating systems"],"product":"Red Hat Hardened Images","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-88834","source_modified_at":"2026-10-13T17:16:43.731Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Hardened Images","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":3.7,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00219,"percentile":0.11766,"score_date":"2026-10-23"},"published_at":"2026-10-13T16:58:04.572Z","modified_at":"2026-10-13T17:16:43.731Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88834","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T17:16:43.731Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88834","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-88834","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531348","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T17:16:29.520798Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-13T17:16:43.731Z","content_hash":"319cd872e4a78fc535e7e61fda99746e837c74bc449147c6106cb6e1fa2a3d5b"}}
