CVE-2026-10595: CWE-23 Relative Path Traversal in parisneo parisneo/lollms
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.
AI Analysis
Technical Summary
The vulnerability exists in the SPA catch-all route implemented in backend/routers/ui.py of parisneo/lollms version 2.1.0. User input is directly joined into a filesystem path without proper sanitization or containment checks. URL-encoded sequences representing '..' (%2e%2e) bypass Starlette's path normalization but are resolved by Python's pathlib, enabling an attacker to perform relative path traversal and read arbitrary files without authentication. The vulnerability is classified as CWE-23 (Relative Path Traversal) and has a CVSS 3.0 score of 7.5 (High). It is resolved in version 3 of the software.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to read arbitrary files on the server, potentially exposing sensitive information. There is no impact on integrity or availability reported. The vulnerability affects confidentiality and could lead to information disclosure.
Mitigation Recommendations
A fix is available in parisneo/lollms version 3. Users should upgrade to version 3 or later to remediate this vulnerability. No official patch link is provided, but upgrading to the fixed version is the recommended action. Until upgraded, users should consider restricting access to the affected route or implementing additional input validation as a temporary mitigation.
