CVE-2026-10595

Summary

A path traversal vulnerability exists in parisneo/lollms version 2.1.0, specifically in the SPA catch-all route implemented in backend/routers/ui.py. The vulnerability arises from the improper handling of user-controlled path input, which is directly joined into a filesystem path without sanitization or containment checks. URL-encoded dot-dot sequences (%2e%2e) bypass Starlette's built-in path normalization and are resolved by Python's pathlib, allowing an unauthenticated attacker to read arbitrary files on the server. This issue has been resolved in version 3.
