[prasunk96]

• vuex-persistedstate version: 2.2.0 and all the versions released after that
• node version: 12.13.0
• npm (or yarn) version: 6.14.7

Problem description:
Snyk had reported High Severity: Prototype Pollution for all the shvl versions released before shvl@2.0.3. The vuex-persistedstate project depends on shvl and therefore became listed as a vulnerable primary dependency in our production project which uses vuex-persistedstate@2.5.4, vue@2.6.10 and vuex@3.1.0. please check below:
