Is this vulnerability remotely exploitable over the network?

Yes. If Parse Server is exposed over the network and configured with the LDAP authentication adapter, any remote user who can reach the authentication endpoint and has valid LDAP credentials can attempt to exploit the injection via crafted login data.

Does an attacker need administrative credentials to exploit this?

No. The issue is exploitable with standard, non-privileged LDAP credentials. The flaw lies in how the application uses the provided identifier in LDAP queries, allowing a regular user to impersonate or appear as a member of restricted groups.

What is the safest general fix pattern?

The safest approach is to eliminate raw string-based LDAP query construction and instead use well-vetted helper functions that: - Properly escape or encode all user-controlled values before inserting them into DNs or filters - Centralize LDAP query building so it can be consistently hardened and reviewed.
