A privilege escalation vulnerability exists in mintplex-labs/anything-llm, allowing users with 'default' role to delete documents uploaded by 'admin'. Despite the intended restriction that prevents 'default' role users from deleting admin-uploaded documents, an attacker can exploit this vulnerability by sending a crafted DELETE request to the /api/system/remove-document endpoint. This vulnerability is due to improper access control checks, enabling unauthorized document deletion and potentially leading to loss of data integrity.
