CVE-2026-75896Network attack vector

LDAP compromise via hard-coded credentials

Published Aug 26, 2026 · Updated Aug 26, 2026

Hard-coded credentials in TÜBİTAK BİLGEM Liderahenk before 3.5.5 allow remote attackers to authenticate to its LDAP service. The CNA identifies LDAP authentication as the locus but does not disclose the file, account, credential value, or code path that embeds and accepts the fixed secret. Network access to LDAP and knowledge of the shared credentials are required, after which directory confidentiality and integrity are compromised without a reported service interruption.
