{"cve":"CVE-2022-31180","nvd":{"published":"2022-08-01T20:15:08.237","modified":"2026-06-17T04:44:58.363","status":"Modified","description":"Shescape is a simple shell escape package for JavaScript. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-74"],"references":["https://github.com/ericcornelissen/shescape/pull/322","https://github.com/ericcornelissen/shescape/pull/324","https://github.com/ericcornelissen/shescape/releases/tag/v1.5.7","https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8","https://github.com/ericcornelissen/shescape/security/advisories/GHSA-44vr-rwwj-p88h"],"products":["shescape_project:shescape"],"source":"nvd","synced_at":"2026-10-19T21:34:18.502168378+00:00"},"epss":{"cve":"CVE-2022-31180","score":0.01993,"percentile":0.80686,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-44vr-rwwj-p88h","url":"https://osv.dev/vulnerability/GHSA-44vr-rwwj-p88h","summary":"Shescape vulnerable to insufficient escaping of whitespace","modified":"2023-11-08T04:09:29.015822Z","packages":[{"ecosystem":"npm","name":"shescape","purl":"pkg:npm/shescape","ranges":[">=1.4.0 <1.5.8"],"fixed":["1.5.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
