Versions of `underscore.deep` prior to version 0.5.3 are vulnerable to a prototype pollution vulnerability. An attacker can craft a malicious payload and pass it to `deepFromFlat`, which would pollute any future Objects created. Any users that have `deepFromFlat` or `deepPick` (due to its dependency on `deepFromFlat`) in their code should upgrade to version 0.5.3 as soon as possible. Users unable to upgrade may mitigate this issue by modifying `deepFromFlat` to prevent specific keywords which will prevent this from happening.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-06-28 18:15:00","updated_at":"2022-07-08 13:40:00"},"problem_types":["CWE-1321"],"metrics":[],"references":[{"url":"https://github.com/Clever/underscore.deep/security/advisories/GHSA-8j79-hfj5-f2xm","name":"https://github.com/Clever/underscore.deep/security/advisories/GHSA-8j79-hfj5-f2xm","refsource":"CONFIRM","tags":[],"title":"Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in underscore.deep · Advisory · Clever/underscore.deep · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/Clever/underscore.deep/commit/b5e109ad05b48371be225fa4d490dd08a94e8ef7","name":"https://github.com/Clever/underscore.deep/commit/b5e109ad05b48371be225fa4d490dd08a94e8ef7","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-8j79-hfj5-f2xm · Clever/underscore.deep@b5e109a · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-31106","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31106","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"31106","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"clever","cpe5":"underscore.deep","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"node.js","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-31106","STATE":"PUBLIC","TITLE":"Prototype Pollution in underscore.deep"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"underscore.deep","version":{"version_data":[{"version_value":"< 0.5.3"}]}}]},"vendor_name":"Clever"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Underscore.deep is a collection of Underscore mixins that operate on nested objects.
