SCA: security update for jpv (GHSA-rh46-3fgc-mvrf)

medium Tenable Cloud Security Plugin ID 422154

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2019-19507)
