{"id":"CVE-2026-102422","summary":"shell-quote `quote()` command injection via a line terminator in a token after a `{ comment }` token","details":"shell-quote's `quote()` function emits a `{ comment }` token as `#` followed by its text, which comments out the rest of the shell line, including the opening quote of any later string token. A line terminator (\\n, \\r, U+2028, U+2029) in that later string therefore ends the comment, and the rest of the string is parsed as shell input: `quote(['echo', 'ok', { comment: 'x' }, 'a\\nid;#'])` runs `id` in sh, bash, dash, ksh and zsh. `parse()` emits a comment token for a `#` in the middle of a word (for example `http://example.com/#frag`), so callers that combine `parse()` output with another untrusted string, such as `quote(parse(untrustedCommand).concat(untrustedArg))`, are affected. The fix for CVE-2026-9277 rejected line terminators in the comment's own text, but not in the tokens after it. Fixed in 1.11.0: `quote()` throws a `TypeError` when a string after a `{ comment }` token contains a line terminator.","aliases":["GHSA-pqg4-j6r4-53mv"],"modified":"2026-10-03T03:45:39.498975950Z","published":"2026-09-29T03:47:36.376Z","database_specific":{"cna_assigner":"harborist","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102422.json"},"references":[{"type":"WEB","url":"https://www.npmjs.com/package/shell-quote"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102422.json"},{"type":"ADVISORY","url":"https://github.com/ljharb/shell-quote/security/advisories/GHSA-pqg4-j6r4-53mv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102422"},{"type":"FIX","url":"https://github.com/ljharb/shell-quote/commit/6002b2ed90c6b83095eb272b6b0adaf3a172b0bc"},{"type":"PACKAGE","url":"https://github.com/ljharb/shell-quote"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ljharb/shell-quote","events":[{"introduced":"ff166e2b63eb5f932bd131a8886a99e9afdf45ae"},{"fixed":"6002b2ed90c6b83095eb272b6b0adaf3a172b0bc"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"1.8.4"},{"fixed":"1.11.0"}]}}],"versions":["v1.10.0","v1.9.0","v1.8.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-102422.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
