The package cached-path-relative before 1.1.0 are vulnerable to Prototype Pollution via the cache variable that is set as {} instead of Object.create(null) in the cachedPathRelative function, which allows access to the parent prototype properties when the object is used to create the cached relative path. When using the origin path as __proto__, the attribute of the object is accessed instead of a path. **Note:** This vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-CACHEDPATHRELATIVE-72573

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    Package        : node-cached-path-relative     Version        : 1.0.1-2+deb10u1     CVE ID         : CVE-2018-16472 CVE-2021-23518     Debian Bug     : #1004338

    Cristian-Alexandru Staicu discovered a prototype pollution vulnerability     in inode-cached-path-relative, a Node.js module used to cache (memoize)     the result of path.relative.

    CVE-2018-16472

        An attacker controlling both the path and the cached value, can         mount a prototype pollution attack and thus overwrite arbitrary         properties on Object.prototype, which may result in denial of         service.

    CVE-2021-23518

        The fix for CVE-2018-16472 was incomplete and other prototype         pollution vulnerabilities were found in the meantime, resulting in a         new CVE.

    For Debian 10 buster, these problems have been fixed in version     1.0.1-2+deb10u1.

    We recommend that you upgrade your node-cached-path-relative packages.
