# Remediation Handoff: CVE-2026-10595

## Summary

NVD: 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. NVD: 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. NVD: 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.

## Safe AI / Codex handoff

* Goal: Prepare a defensive remediation plan for CVE-2026-10595 using only provided public-safe source context and any separate repo context supplied by the user.
* Allowed actions: summarize vendor guidance, prepare a defensive remediation plan, identify affected dependencies only when repo context is separately provided by the user, suggest tests and validation steps, document human verification questions
* Disallowed actions: generate offensive code, provide payloads, scan external targets, change production systems, merge or deploy changes, create GitHub issues or pull requests without explicit separate approval
* Acceptance criteria: Affected product or dependency presence is confirmed by a human., Affected version is confirmed or marked not applicable., Official advisory or source reference is reviewed., Patch, fixed version, mitigation, workaround, or monitor-only decision is documented., Validation steps are proposed without external scanning or production mutation.
* Human approval required: true
