## Summary

Dexmal Dexbotic (versions up to 0.2.0) is affected through its gr00tsonic checkpoint loader, where improper handling of a file path argument allows an attacker to access files outside the intended directory. This path traversal flaw can be triggered remotely, potentially exposing sensitive files on the system.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Dexmal Dexbotic: 0.1, 0.2.0

## Description

A flaw has been found in Dexmal Dexbotic up to 0.2.0.
