  "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.\n\n\n## Affected Endpoint\n\n| Endpoint | Auth Required | Injection Parameter |\n|----------|--------------|---------------------|\n| `GET /openam/json/{realm}/users?_queryId=\u003cINJECTION\u003e` | SSO Token | `_queryId` |\n| `GET /openam/json/{realm}/groups?_queryId=\u003cINJECTION\u003e` | SSO Token (TBD) | `_queryId` |\n\n## Background: CVE-2021-29156\n\nCVE-2021-29156 was a pre-authentication LDAP injection in OpenAM\u0027s 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:\n\n## Credit\n\nDiscovered by **JD-Security SHENYI Team**",
