Solution
No solution given by the vendor.
Workaround
No direct workaround addresses the code-level bug; network-level mitigations (proxies, WAFs, filter validation) do not apply. Mitigation measures to reduce exposure: restrict plugin configuration access (MEP originFilter, UID uniqueness nsUniqueAttribute, strict ACIs on cn=config); restrict Directory Manager access for ACI, MEP, or uniqueness plugin configuration; harden replication topology to restrict replication peers; monitor for anomalous search result sets that may indicate exploitation.
