Affected versions were found to have insufficient escaping of white space when interpolating output. This issue only impacts users that use the `escape` or `escapeAll` functions with the `interpolation` option set to `true`. The result is that if an attacker is able to include whitespace in their input they can: 1. Invoke shell-specific behaviour through shell-specific special characters inserted directly after whitespace. 2. Invoke shell-specific behaviour through shell-specific special characters inserted or appearing after line terminating characters. 3. Invoke arbitrary commands by inserting a line feed character. 4. Invoke arbitrary commands by inserting a carriage return character. Behaviour number 1 has been patched in [v1.5.7] which you can upgrade to now. No further changes are required. Behaviour number 2, 3, and 4 have been patched in [v1.5.8] which you can upgrade to now. No further changes are required. The best workaround is to avoid having to use the `interpolation: true` option - in most cases using an alternative is possible, see [the recipes](https://github.com/ericcornelissen/shescape#recipes) for recommendations. Alternatively, users may strip all whitespace from user input. Note that this is error prone, for example: for PowerShell this requires stripping `'\\u0085'` which is not included in JavaScript's definition of `\\s` for Regular Expressions.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-08-01 20:15:00","updated_at":"2023-07-24 13:07:00"},"problem_types":["NVD-CWE-Other"],"metrics":[],"references":[{"url":"https://github.com/ericcornelissen/shescape/releases/tag/v1.5.7","name":"https://github.com/ericcornelissen/shescape/releases/tag/v1.5.7","refsource":"MISC","tags":[],"title":"Release Release v1.5.7 · ericcornelissen/shescape · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8","name":"https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8","refsource":"MISC","tags":[],"title":"Release Release v1.5.8 · ericcornelissen/shescape · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/ericcornelissen/shescape/pull/324","name":"https://github.com/ericcornelissen/shescape/pull/324","refsource":"MISC","tags":[],"title":"Escaping for Unix shells after whitespace with `{interpolation:true}` by ericcornelissen · Pull Request #324 · ericcornelissen/shescape · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/ericcornelissen/shescape/security/advisories/GHSA-44vr-rwwj-p88h","name":"https://github.com/ericcornelissen/shescape/security/advisories/GHSA-44vr-rwwj-p88h","refsource":"CONFIRM","tags":[],"title":"Insufficient escaping of whitespace · Advisory · ericcornelissen/shescape · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://github.com/ericcornelissen/shescape/pull/322","name":"https://github.com/ericcornelissen/shescape/pull/322","refsource":"MISC","tags":[],"title":"Escaping for PowerShell after whitespace with `{interpolation:true}` by ericcornelissen · Pull Request #322 · ericcornelissen/shescape · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-31180","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31180","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"31180","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"shescape_project","cpe5":"shescape","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-31180","STATE":"PUBLIC","TITLE":"Insufficient escaping of whitespace in shescape"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"shescape","version":{"version_data":[{"version_value":">=1.4.0 < 1.5.8"}]}}]},"vendor_name":"ericcornelissen"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Shescape is a simple shell escape package for JavaScript.
