{"id":"CVE-2022-21189","summary":"Prototype Pollution","details":"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":["GHSA-3xgx-r9j4-qw9w"],"modified":"2026-08-12T03:51:38.134167397Z","published":"2022-05-01T15:25:21.478Z","related":["SNYK-JAVA-ORGWEBJARSNPM-2805308","SNYK-JS-DEXIE-2607042"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/21xxx/CVE-2022-21189.json","cna_assigner":"snyk"},"references":[{"type":"WEB","url":"https://github.com/dexie/Dexie.js/blob/fe682ef24568278c3b31d9d6c93de095d4b77ae8/src/functions/utils.ts%23L134-L164"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/21xxx/CVE-2022-21189.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-21189"},{"type":"ADVISORY","url":"https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-2805308"},{"type":"ADVISORY","url":"https://snyk.io/vuln/SNYK-JS-DEXIE-2607042"},{"type":"FIX","url":"https://github.com/dexie/Dexie.js/commit/1d655a69b9f28c3af6fae10cf5c61df387dc689b"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dexie/dexie.js","events":[{"introduced":"0"},{"fixed":"c698052360bd0b0d958ff38d74933f15f9f83909"},{"fixed":"1d655a69b9f28c3af6fae10cf5c61df387dc689b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.2.2"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:dexie:dexie:*:*:*:*:*:node.js:*:*"}}],"versions":["4.0.0-alpha.1","v3.0.0-alpha.4","v1.4.0-beta","v1.3.1","v1.3.0","v1.2.0","v1.2","v1.1.0","v1.1","v1.0.4","v1.0.3","v1.0.2","v1.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-21189.json"}}],"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/E:P"}]}
