The Preset configuration https://v2.vuetifyjs.com/en/features/presets feature of Vuetify is vulnerable to Prototype Pollution https://cheatsheetseries.owasp.org/cheatsheets/Prototype_Pollution_Prevention_Cheat_Sheet.html 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 applications 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/ .
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
