{"id":"AZL-108318","summary":"CVE-2026-88834 affecting package busybox 1.36.1-27","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.","modified":"2026-10-20T05:35:13Z","published":"2026-10-13T17:17:48Z","upstream":["CVE-2026-88834"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88834"}],"affected":[{"package":{"name":"busybox","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/busybox"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.36.1-27"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108318.json"}}],"schema_version":"1.9.0"}
