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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Directory Server 11","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/a:redhat:directory_server:11"]},{"vendor":"Red Hat","product":"Red Hat Directory Server 12","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/a:redhat:directory_server:12"]},{"vendor":"Red Hat","product":"Red Hat Directory Server 13","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/a:redhat:directory_server:13"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:10"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"unknown","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"389-ds-base","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-19404","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2513036","name":"RHBZ#2513036","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-08-10T07:56:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-862","description":"Missing Authorization","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-862: Missing Authorization","workarounds":[{"lang":"en","value":"Set nsslapd-allow-anonymous-access to rootdse or off as an interim mitigation.
