The Preset configuration feature of Vuetify is vulnerable to Prototype Pollution due to the internal 'mergeDeep' utility function used to merge options with defaults. Using a specially-crafted, malicious preset can result in polluting all JavaScript objects with arbitrary properties, which can further negatively affect all aspects of the application's behavior. This can lead to a wide range of security issues, including resource exhaustion/denial of service or unauthorized access to data.
If the application utilizes Server-Side Rendering (SSR), this vulnerability could affect the whole server process.
This issue affects Vuetify versions greater than or equal to 2.2.0-beta.2 and less than 3.0.0-alpha.10.
Note: Version 2.x of Vuetify is End-of-Life and will not receive any updates to address this issue. For more information see here https://v2.vuetifyjs.com/en/about/eol/ .
