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."}], "metrics": [{"cvssV3_1": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 9.8, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}}], "problemTypes": [{"descriptions": [{"cweId": "CWE-74", "description": "CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')", "lang": "en", "type": "CWE"}]}], "providerMetadata": {"dateUpdated": "2022-08-01T19:15:16.000Z", "orgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "shortName": "GitHub_M"}, "references": [{"tags": ["x_refsource_CONFIRM"], "url": "https://github.com/ericcornelissen/shescape/security/advisories/GHSA-44vr-rwwj-p88h"}, {"tags": ["x_refsource_MISC"], "url": "https://github.com/ericcornelissen/shescape/pull/322"}, {"tags": ["x_refsource_MISC"], "url": "https://github.com/ericcornelissen/shescape/pull/324"}, {"tags": ["x_refsource_MISC"], "url": "https://github.com/ericcornelissen/shescape/releases/tag/v1.5.7"}, {"tags": ["x_refsource_MISC"], "url": "https://github.com/ericcornelissen/shescape/releases/tag/v1.5.8"}], "source": {"advisory": "GHSA-44vr-rwwj-p88h", "discovery": "UNKNOWN"}, "title": "Insufficient escaping of whitespace in shescape", "x_legacyV4Record": {"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.
