How to Fix CVE-2024-6139

To remediate this vulnerability, upgrade all affected Lollms dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

lollms fixed: Latest secure release 
pip install lollms>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show lollms

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-6139, inspect your installed packages using pip:

pip show lollms

Analyze the terminal output to locate any version of Lollms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show lollms command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-29: Path Traversal: '\..\filename', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory. In Lollms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A path traversal vulnerability exists in the XTTS server of the parisneo/lollms package version v9.6. This vulnerability allows an attacker to write audio files to arbitrary locations on the system and enumerate file paths. The issue arises from improper validation of user-provided file paths in the `tts_to_file` endpoint.
