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.
