CVE-2026-11770

HIGH

7.5

CVSS v3

Description

A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.

Common questions

How do I fix CVE-2026-11770?

Published advisories record a fix for 132 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.

Is CVE-2026-11770 being actively exploited?

Not that we know of. CVE-2026-11770 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.53% is the estimated probability that it will be exploited in the next 30 days. That is higher than 43% of all scored CVEs.

How severe is CVE-2026-11770?

CVE-2026-11770 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2026-11770 affect?

Published advisories record a fix for 389-ds-base (Red Hat / RHEL), 389-ds-base (Rocky), 389-ds-base-0:1.4.3.34 (Red Hat / RHEL), 389-ds-base-0:1.4.3.34 (Rocky), and 128 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
