CVE-2026-103880

[Support]

CVE-2026-103880
Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API.



Storing a password using the bcrypt algorithm with a high force like 30 in a LDAP server that supports this algorithm will cause the server CPU to run for hours checking the credentials. A bounded cost should be enforced to avoid a server DOS.



This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.



Users are recommended to upgrade to version 2.1.9, which fixes the issue.
