A vulnerability allowing unrestricted file upload has been identified in PromtEngineer localGPT versions through 4d41c7d1713b16b216d8e062e51a5dd88b20b054. The issue resides in the 'do_POST' function of 'backend/server.py', where uploaded files are not subjected to authentication, type validation, size restrictions, or rate limiting. This flaw can be exploited remotely, leading to server disk space exhaustion and causing a denial-of-service condition that impacts all users.
It is recommended to implement authentication for file uploads, add file type validation, impose size limits, introduce rate limiting, sanitize filenames to prevent path traversal, and establish storage quotas.
