# Path traversal in a Python file handler — Agent PR X-Ray

> Canonical page: https://codevetter.com/xray/py-path-traversal

This is an adjudicated synthetic benchmark example, not a claim about an uploaded repository.

## Source

- Corpus: codevetter-public-benchmark/py-path-traversal
- Language: Python
- Category: Security
- Evidence state: benchmark_ground_truth

## Finding

- Severity: high
- Title: Untrusted path escapes the intended directory
- Summary: The requested filename is joined to the storage root without canonical containment validation.
- Source anchor: `source.py:9`

## Verification boundary

The static finding is qualified against benchmark ground truth. No exact-current executable test or audience validation is included in this example, so those stages remain unverified.
