How broadly exploitable is this vulnerability?

Exploitation is limited to authenticated users of the affected LibreChat instance, but within that scope, any user who can obtain a target agent's ID may be able to manipulate that agent's file context and behavior, especially in shared or multi-user environments.

Does an attacker need elevated privileges or admin access?

No elevated privileges are inherently required; a regular authenticated account is sufficient if the attacker can reference the target agent ID. The flaw lies in missing authorization checks, not in bypassing authentication.

What is the safest general fix pattern for developers?

Implement strict, server-side authorization for every operation that modifies an agent, especially file uploads and search indexing. Each request should verify that the acting user has explicit rights (ownership, role, or ACL entry) to change the referenced agent's resources, rather than trusting the presence of an agent ID.
