CVE-2019-19507 (GCVE-0-2019-19507)

Vulnerability from cvelistv5 – Published: 2019-12-02 16:17 – Updated: 2024-08-05 02:16

Summary

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.

Severity ?

No CVSS data available.
