{"id":"UBUNTU-CVE-2026-102422","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.","modified":"2026-09-29T23:41:45.414948995Z","published":"2026-09-29T00:00:00Z","upstream":["CVE-2026-102422"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-102422"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-102422"},{"type":"REPORT","url":"https://github.com/ljharb/shell-quote"},{"type":"REPORT","url":"https://github.com/ljharb/shell-quote/commit/6002b2ed90c6b83095eb272b6b0adaf3a172b0bc"},{"type":"REPORT","url":"https://github.com/ljharb/shell-quote/security/advisories/GHSA-pqg4-j6r4-53mv"},{"type":"REPORT","url":"https://www.npmjs.com/package/shell-quote"}],"affected":[{"package":{"name":"node-shell-quote","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/node-shell-quote?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.1+20160617-git72fb5a8ce29b-1","1.6.1+20160617-git72fb5a8ce29b-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-shell-quote","binary_version":"1.6.1+20160617-git72fb5a8ce29b-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102422.json"}},{"package":{"name":"node-shell-quote","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/node-shell-quote?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.3+~1.7.1-1","1.7.3+~1.7.1-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-shell-quote","binary_version":"1.7.3+~1.7.1-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102422.json"}},{"package":{"name":"node-shell-quote","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-shell-quote?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.4+~1.7.1-1","1.7.4+~1.7.1-1ubuntu0.24.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.7.4+~1.7.1-1ubuntu0.24.04.1","binary_name":"node-shell-quote"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102422.json"}},{"package":{"name":"node-shell-quote","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/node-shell-quote?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.4+~1.7.1-1","1.8.3+~1.7.5-1","1.8.3+~1.7.5-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3+~1.7.5-1ubuntu0.1~esm1","binary_name":"node-shell-quote"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102422.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
