CVE-2026-41573

EUVD-2026-78366

15.09.2026, 10:17

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, IdentityResourceV1.queryCollection() passes the _queryId parameter from /json/{realm}/users to CrestQuery with escapeQueryId disabled, bypassing protection added for CVE-2021-29156. The unescaped value reaches DJLDAPv3Repo.getFilter(), where it is concatenated into an LDAP filter, allowing an authenticated attacker to inject LDAP metacharacters for user enumeration and blind LDAP injection. This issue is fixed in version 16.1.1.

Common Weakness Enumeration

CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')
The software constructs all or part of an LDAP query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended LDAP query when it is sent to a downstream component.
