Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Soft Serve is a self-hostable Git server for the command line. From version 0.6.0 to before version 0.11.4, an authenticated SSH user can force the server to make HTTP requests to internal/private IP addresses by running repo import with a crafted --lfs-endpoint URL. The initial batch request is blind (the response from a metadata endpoint won't parse as valid LFS JSON), but an attacker hosting a fake LFS server can chain this into full read access to internal services by returning download URLs that point at internal targets. This issue has been patched in version 0.11.4.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-918

The server can be induced to make requests to a URL an attacker controls, turning it into a proxy into internal networks and cloud metadata services. It's especially dangerous behind a trusted network boundary. The fix is strict allow-listing of destinations and blocking access to internal address ranges.

Upgrade available Upgrade to 0.11.4 or later
Fixed in 0.11.4

Recommended fix High confidence

0.11.4

  1. 1. Identify the currently installed Soft Serve version (e.g., via `soft-serve --version` or checking the binary)
  2. 2. If version is >= 0.6.0 and < 0.11.4, the instance is vulnerable
  3. 3. Back up the Soft Serve configuration and data directories before upgrading
  4. 4. Upgrade Soft Serve to version 0.11.4 or later by downloading the new release from https://github.com/charmbracelet/soft-serve/releases
  5. 5. Verify the upgrade was successful by checking the new version number
  6. 6. Review server logs to check for any past exploitation attempts targeting the LFS endpoint
