  "summary" : "Shescape prior to 1.5.8 vulnerable to insufficient escaping of line feeds for CMD",
  "details" : "### Impact\n\nThis impacts users that use Shescape (any API function) to escape arguments for **cmd.exe** on **Windows**. An attacker can omit all arguments following their input by including a line feed character (`'\\n'`) in the payload. Example:\n\n```javascript\nimport cp from \"node:child_process\";\nimport * as shescape from \"shescape\";\n\n// 1. Prerequisites\nconst options = {\n  shell: \"cmd.exe\",\n};\n\n// 2. Attack\nconst payload = \"attacker\\n\";\n\n// 3. Usage\nlet escapedPayload;\nescapedPayload = shescape.escape(payload, options);\n// Or\nescapedPayload = shescape.escapeAll([payload], options)[0];\n// Or\nescapedPayload = shescape.quote(payload, options);\n// Or\nescapedPayload = shescape.quoteAll([payload], options)[0];\n\ncp.execSync(`echo Hello ${escapedPayload}! How are you doing?`, options);\n// Outputs:  \"Hello attacker\"\n```\n\n> **Note**: `execSync` is just illustrative here, all of `exec`, `execFile`, `execFileSync`, `fork`, `spawn`, and `spawnSync` can be attacked using a line feed character if CMD is the shell being used.\n\n### Patches\n\nThis bug has been patched in [v1.5.8] which you can upgrade to now. No further changes are required.\n\n### Workarounds\n\nAlternatively, line feed characters (`'\\n'`) can be stripped out manually or the user input can be made the last argument (this only limits the impact).\n\n### References\n\n- https://github.com/ericcornelissen/shescape/pull/332\n- https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Comment on https://github.com/ericcornelissen/shescape/pull/332\n- Open an issue at https://github.com/ericcornelissen/shescape/issues (_New issue_ > _Question_ > _Get started_)\n\n[v1.5.8]: https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8\n",
