CVE-2026-41573: OpenAM has LDAP Injection via `_queryId` Parameter

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.
