CVE-2026-41573 (GCVE-0-2026-41573)

Vulnerability from cvelistv5 – Published: 2026-09-15 09:55 – Updated: 2026-09-15 12:41

Title

OpenAM LDAP Injection via `_queryId` Parameter

Summary

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.

Severity

7.1 (High)

GHSA-2VG8-Q4C2-5CW3

Vulnerability from github – Published: 2026-06-22 19:59 – Updated: 2026-06-22 19:59

Summary

OpenAM has LDAP Injection via `_queryId` Parameter

Details

OpenAM (Open Identity Platform) is an open-source IAM platform providing SSO, OAuth2, SAML, and OpenID Connect capabilities. The CREST REST API layer exposes user query endpoints under /json/{realm}/users. In IdentityResourceV1.queryCollection(), the HTTP query parameter _queryId is passed to a CrestQuery object with escapeQueryId explicitly set to false, bypassing the escape protection introduced as part of the CVE-2021-29156 fix. The unescaped value flows directly to DJLDAPv3Repo.getFilter() where it is concatenated into an LDAP filter string without sanitization, enabling authenticated attackers to inject arbitrary LDAP metacharacters for user enumeration and blind LDAP injection.

Affected Endpoint

Endpoint	Auth Required	Injection Parameter
`GET /openam/json/{realm}/users?_queryId=<INJECTION>`	SSO Token	`_queryId`
`GET /openam/json/{realm}/groups?_queryId=<INJECTION>`	SSO Token (TBD)	`_queryId`

Background: CVE-2021-29156

CVE-2021-29156 was a pre-authentication LDAP injection in OpenAM's Webfinger endpoint, where user-supplied input reached DJLDAPv3Repo.getFilter() unescaped. The fix introduced the escapeQueryId flag in CrestQuery (defaulting to true) and added Filter.escapeAssertionValue() in the filter-building path:
