{"id":"UBUNTU-CVE-2020-15256","details":"A prototype pollution vulnerability has been found in `object-path` \u003c= 0.11.4 affecting the `set()` method. The vulnerability is limited to the `includeInheritedProps` mode (if version \u003e= 0.11.0 is used), which has to be explicitly enabled by creating a new instance of `object-path` and setting the option `includeInheritedProps: true`, or by using the default `withInheritedProps` instance. The default operating mode is not affected by the vulnerability if version \u003e= 0.11.0 is used. Any usage of `set()` in versions \u003c 0.11.0 is vulnerable. The issue is fixed in object-path version 0.11.5 As a workaround, don't use the `includeInheritedProps: true` options or the `withInheritedProps` instance if using a version \u003e= 0.11.0.","modified":"2026-02-04T03:48:29.728250Z","published":"2020-10-19T22:15:00Z","related":["USN-5967-1"],"upstream":["CVE-2020-15256"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-15256"},{"type":"REPORT","url":"https://github.com/mariocasciaro/object-path/security/advisories/GHSA-cwx2-736x-mf6w"},{"type":"REPORT","url":"https://github.com/mariocasciaro/object-path/commit/2be3354c6c46215c7635eb1b76d80f1319403c68"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5967-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-15256"}],"affected":[{"package":{"name":"node-object-path","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-object-path@0.11.3-1ubuntu0.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.3-1ubuntu0.1"}]}],"versions":["0.11.3-1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"0.11.3-1ubuntu0.1","binary_name":"node-object-path"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-15256.json"}},{"package":{"name":"node-object-path","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-object-path@0.11.4-2ubuntu0.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.4-2ubuntu0.1"}]}],"versions":["0.11.4-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"node-object-path","binary_version":"0.11.4-2ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-15256.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H"},{"type":"Ubuntu","score":"low"}]}
