What is CVE-2026-30832?
CVE-2026-30832 is a critical server-side request forgery vulnerability in charmbracelet soft-serve, published on 7 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-918
