How to Fix CVE-2025-22130

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

github.com/charmbracelet/soft-serve fixed: 0.8.2 
Upgrade github.com/charmbracelet/soft-serve to 0.8.2
Verify Direct and Transitive Dependencies

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

inspect dependencies for github.com/charmbracelet/soft-serve

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-22130, inspect your project dependencies for Github.com/charmbracelet/soft serve:

inspect dependencies for github.com/charmbracelet/soft-serve

Analyze the terminal output to locate any version of Github.com/charmbracelet/soft serve in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/charmbracelet/soft serve, 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

### Impact Path traversal attack gives access to existing non-admin users to access and take over other user's repositories. A malicious user then can modify, delete, and arbitrarily repositories as if they were an admin user without explicitly giving them permissions. ### Patches This is patched in [v0.8.2](https://github.com/charmbracelet/soft-serve/releases/tag/v0.8.2) ### Workarounds Single user set-ups are not affected. This only affects multi-user Soft Serve set-ups that enable repository creation for users. Otherwise, upgrading is necessary to circumvent the attack.
