AdonisJS is a TypeScript-first web framework. From 10.1.3 until 10.1.5 and 11.0.3, AdonisJS @adonisjs/bodyparser incompletely fixed CVE-2026-25754 because nested multipart field payloads such as user.proto.polluted and constructor.prototype still caused lodash _.set() via @poppinss/utils to create plain intermediate objects and pollute Object.prototype. This issue is fixed in versions 10.1.5 and 11.0.3.
