{"id":"CVE-2019-19507","aliases":[],"url":"https://o3.security/vulnerability/CVE-2019-19507","summary":"Validation bypass is possible in Json Pattern Validator","details":"In jpv (aka Json Pattern Validator) before 2.1.1, compareCommon() can be bypassed because certain internal attributes can be overwritten via a conflicting name, as demonstrated by 'constructor': {'name':'Array'}. This affects validate(). Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.","published":"2019-12-04T21:25:28Z","modified":"2023-11-08T04:01:28.483830Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"jpv","fixedVersion":"2.1.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-19507"},{"type":"WEB","url":"https://github.com/manvel-khnkoyan/jpv/issues/6"},{"type":"WEB","url":"https://www.npmjs.com/package/jpv"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:01:28.483830Z"}}
