{"id":"CVE-2021-23434","details":"This affects the package object-path before 0.11.6. A type confusion vulnerability can lead to a bypass of CVE-2020-15256 when the path components used in the path parameter are arrays. In particular, the condition currentPath === '__proto__' returns false if currentPath is ['__proto__']. This is because the === operator returns always false when the type of the operands is different.","aliases":["GHSA-v39p-96qg-c8rf"],"modified":"2026-03-14T10:46:59.612813Z","published":"2021-08-27T17:15:06.910Z","related":["SNYK-JAVA-ORGWEBJARSNPM-1570423","SNYK-JS-OBJECTPATH-1569453"],"references":[{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2023/01/msg00031.html"},{"type":"FIX","url":"https://github.com/mariocasciaro/object-path/commit/7bdf4abefd102d16c163d633e8994ef154cab9eb"},{"type":"PACKAGE","url":"https://github.com/mariocasciaro/object-path%230116"},{"type":"EVIDENCE","url":"https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1570423"},{"type":"EVIDENCE","url":"https://snyk.io/vuln/SNYK-JS-OBJECTPATH-1569453"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mariocasciaro/object-path","events":[{"introduced":"0"},{"fixed":"94f92d8932fce12eeff853116646160477c6ce11"},{"fixed":"7bdf4abefd102d16c163d633e8994ef154cab9eb"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.11.6"}]}}],"versions":["v0.1.0","v0.1.2","v0.1.3","v0.10.0","v0.11.0","v0.2.0","v0.2.1","v0.3.0","v0.4.0","v0.5.1","v0.6.0","v0.7.0","v0.8.0","v0.8.1","v0.9.0","v0.9.1","v0.9.2","v0.9.3"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-23434.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
