{"id":"CVE-2026-19404","state":"PUBLISHED","title":"389-ds-base: 389-ds-base: missing authorization allows anonymous clients to start or abort cleanallruv replication maintenance","description":"A flaw was found in 389 Directory Server. The CleanAllRUV and Abort CleanAllRUV replication-maintenance extended operations perform no authorization check, allowing an unauthenticated remote attacker to invoke them when nsslapd-allow-anonymous-access is enabled (the default), or any authenticated low-privilege user to invoke them otherwise. This allows removal of a replica ID from replication metadata, purging of changelog records, and interruption of administrator-initiated cleanup, which can leave replication inconsistent or unavailable.","publishedAt":"2026-08-10T09:38:10.790Z","updatedAt":"2026-08-10T21:11:24.632Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","source":"redhat"},"assigner":"redhat","products":["Red Hat Red Hat Directory Server 11","Red Hat Red Hat Directory Server 12","Red Hat Red Hat Directory Server 13","Red Hat Red Hat Enterprise Linux 10","Red Hat Red Hat Enterprise Linux 6","Red Hat Red Hat Enterprise Linux 7","Red Hat Red Hat Enterprise Linux 8","Red Hat Red Hat Enterprise Linux 9"],"affected":[{"vendor":"Red Hat","product":"Red Hat Directory Server 11","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:directory_server:11"]},{"vendor":"Red Hat","product":"Red Hat Directory Server 12","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:directory_server:12"]},{"vendor":"Red Hat","product":"Red Hat Directory Server 13","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:directory_server:13"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:10"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","packageName":"389-ds-base","defaultStatus":"unknown","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"389-ds-base","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":["https://access.redhat.com/security/cve/CVE-2026-19404","https://bugzilla.redhat.com/show_bug.cgi?id=2513036"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19404.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19404","state":"PUBLISHED","datePublished":"2026-08-10T09:38:10.790Z","dateUpdated":"2026-08-10T21:11:24.632Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-08-10T07:55:45.246Z"},"containers":{"cna":{"title":"389-ds-base: 389-ds-base: missing authorization allows anonymous clients to start or abort cleanallruv replication maintenance","descriptions":[{"lang":"en","value":"A flaw was found in 389 Directory Server.
