Hi,
The following vulnerability was published for libgit2.
CVE-2026-5917[0]:
| libgit2 versions v0.27.0 through v1.9.0 built with the libssh2 SSH
| backend (USE_SSH=libssh2) contain a shell command injection
| vulnerability that allows remote attackers to execute arbitrary
| commands on an SSH server by supplying a repository path containing
| unescaped shell metacharacters such as single quotes, semicolons, or
| pipes. The gen_proto() function in ssh_libssh2.c inserts the
| repository path directly into a shell command string without
| escaping special characters before passing it to
| libssh2_channel_exec(), enabling an attacker to craft a malicious
| submodule URL in a .gitmodules file that, when processed during a
| recursive clone, causes the remote server's shell to interpret
| injected commands under the victim's SSH user account.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
