# Remediation Handoff: CVE-2026-102422

## Summary

NVD: 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. NVD: 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. NVD: parse() emits a comment token for a # in the middle of a word (for example so callers that combine parse() output with another untrusted string, such as quote(parse(untrustedCommand).concat(untrustedArg)), are affected.

## Safe AI / Codex handoff

* Goal: Prepare a defensive remediation plan for CVE-2026-102422 using only provided public-safe source context and any separate repo context supplied by the user.
* Allowed actions: summarize vendor guidance, prepare a defensive remediation plan, identify affected dependencies only when repo context is separately provided by the user, suggest tests and validation steps, document human verification questions
* Disallowed actions: generate offensive code, provide payloads, scan external targets, change production systems, merge or deploy changes, create GitHub issues or pull requests without explicit separate approval
* Acceptance criteria: Affected product or dependency presence is confirmed by a human., Affected version is confirmed or marked not applicable., Official advisory or source reference is reviewed., Patch, fixed version, mitigation, workaround, or monitor-only decision is documented., Validation steps are proposed without external scanning or production mutation.
* Human approval required: true
