CVE-2026-30832Public exploitNetwork attack vector

Authenticated SSRF via unvalidated LFS endpoint

Published Mar 7, 2026 · Updated Mar 7, 2026

SSRF in Soft Serve 0.6.0 through 0.11.3 allows remote authenticated users to read internal HTTP services through SSH repo import. The repo import command passes the user-controlled --lfs-endpoint into an LFS client backed by http.DefaultClient, which does not block private addresses or redirects. Any valid SSH key and an imported repository containing LFS pointers are sufficient; a fake LFS batch response can redirect downloads to internal targets and store their bodies for later retrieval.
