{"id":"DEBIAN-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":"2026-10-01T02:47:48.159442849Z","published":"2026-09-29T04:17:55.707Z","upstream":["CVE-2026-102422"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-102422"}],"affected":[{"package":{"name":"node-shell-quote","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-shell-quote?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.0-1","1.7.4+~1.7.1-1","1.7.4+~1.7.1-1+deb12u1","1.7.4+~1.7.1-2","1.8.3+~1.7.5-1","1.8.4+~1.7.5-1","1.9.0+~1.7.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-102422.json"}},{"package":{"name":"node-shell-quote","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-shell-quote?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.0-1","1.7.4+~1.7.1-1","1.7.4+~1.7.1-1+deb13u1","1.7.4+~1.7.1-2","1.8.3+~1.7.5-1","1.8.4+~1.7.5-1","1.9.0+~1.7.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-102422.json"}},{"package":{"name":"node-shell-quote","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-shell-quote?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.0-1","1.7.4+~1.7.1-1","1.7.4+~1.7.1-2","1.8.3+~1.7.5-1","1.8.4+~1.7.5-1","1.9.0+~1.7.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
