Hi,

The following vulnerability was published for node-shell-quote.

CVE-2026-102422[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
