{"id":"GHSA-3xgx-r9j4-qw9w","summary":"Prototype Pollution in Dexie","details":"Dexie is a minimalistic wrapper for IndexedDB. The package dexie before 3.2.2, from 4.0.0-alpha.1 and before 4.0.0-alpha.3 are vulnerable to Prototype Pollution in the Dexie.setByKeyPath(obj, keyPath, value) function which does not properly check the keys being set (like __proto__ or constructor). This can allow an attacker to add/modify properties of the Object.prototype leading to prototype pollution vulnerability. **Note:** This vulnerability can occur in multiple ways, for example when modifying a collection with untrusted user input.","aliases":["CVE-2022-21189"],"modified":"2025-01-08T14:11:54.925904Z","published":"2022-05-03T00:00:46Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-05-23T20:12:28Z","nvd_published_at":"2022-05-01T16:15:00Z","cwe_ids":["CWE-1321"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-21189"},{"type":"WEB","url":"https://github.com/dexie/Dexie.js/commit/1d655a69b9f28c3af6fae10cf5c61df387dc689b"},{"type":"PACKAGE","url":"https://github.com/dexie/Dexie.js"},{"type":"WEB","url":"https://github.com/dexie/Dexie.js/blob/fe682ef24568278c3b31d9d6c93de095d4b77ae8/src/functions/utils.ts%23L134-L164"},{"type":"WEB","url":"https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-2805308"},{"type":"WEB","url":"https://snyk.io/vuln/SNYK-JS-DEXIE-2607042"}],"affected":[{"package":{"name":"dexie","ecosystem":"npm","purl":"pkg:npm/dexie"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-3xgx-r9j4-qw9w/GHSA-3xgx-r9j4-qw9w.json"}},{"package":{"name":"dexie","ecosystem":"npm","purl":"pkg:npm/dexie"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0-alpha.1"},{"fixed":"4.0.0-alpha.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-3xgx-r9j4-qw9w/GHSA-3xgx-r9j4-qw9w.json","last_known_affected_version_range":"\u003c= 4.0.0-alpha.2"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
