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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-102422)\n\nAffected packages:\n\n- `shell-quote >= 1.8.4, < 1.11.0`\n\nPatched in:\n\n- `shell-quote 1.11.0`\n\nSource: https://github.com/advisories/GHSA-pqg4-j6r4-53mv\n\n## Vendor advisories\n\n- **RHSA-2026:72498** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:72498)\n- **RHSA-2026:72507** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:72507)\n- **RHSA-2026:69544** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69544)\n- **RHSA-2026:72750** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:72750)\n- **Red Hat VEX** · Important · affected: OpenShift Lightspeed, OpenShift Pipelines, Red Hat Connectivity Link 1, Red Hat Discovery 2, Red Hat OpenShift AI (RHOAI), Red Hat OpenShift Dev Spaces, … · no fix planned: Secrets Management Console for Red Hat OpenShift, OpenShift Lightspeed, OpenShift Pipelines, Red Hat Connectivity Link 1, … · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-102422.json)","depth":"midnight","depthScore":57,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":217937,"id":"CVE-2026-102422","ts":1791452372143,"field":"exploit_available","old":"false","new":"true"}]}
