{"id":"GHSA-p92x-r36w-9395","summary":"Type confusion in mpath","details":"This affects the package mpath before 0.8.4. A type confusion vulnerability can lead to a bypass of CVE-2018-16490. In particular, the condition `ignoreProperties.indexOf(parts[i]) !== -1` returns `-1` if `parts[i]` is `['__proto__']`. This is because the method that has been called if the input is an array is `Array.prototype.indexOf()` and not `String.prototype.indexOf()`. They behave differently depending on the type of the input.","aliases":["CVE-2021-23438"],"modified":"2025-01-08T10:42:05.906784Z","published":"2021-09-02T22:02:25Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2021-09-02T17:06:28Z","nvd_published_at":"2021-09-01T19:15:00Z","cwe_ids":["CWE-843"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-23438"},{"type":"WEB","url":"https://github.com/aheckmann/mpath/commit/89402d2880d4ea3518480a8c9847c541f2d824fc"},{"type":"WEB","url":"https://github.com/mongoosejs/mpath/commit/89402d2880d4ea3518480a8c9847c541f2d824fc"},{"type":"PACKAGE","url":"https://github.com/aheckmann/mpath"},{"type":"WEB","url":"https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1579548"},{"type":"WEB","url":"https://snyk.io/vuln/SNYK-JS-MPATH-1577289"}],"affected":[{"package":{"name":"mpath","ecosystem":"npm","purl":"pkg:npm/mpath"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/09/GHSA-p92x-r36w-9395/GHSA-p92x-r36w-9395.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
