CVE-2026-30832: Soft Serve: SSRF via unvalidated LFS endpoint in repo import

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.34% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: charmbracelet soft-serve 0.11.4.

Low priority for now. Upgrade to charmbracelet soft-serve 0.11.4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
