Summary

The vulnerability in AdonisJS @adonisjs/bodyparser incompletely fixes CVE-2026-25754, allowing prototype pollution attacks via nested multipart fields like user.__proto__.polluted, which cause lodash _.set() via @poppinss/utils to create plain intermediate objects and pollute Object.prototype.

Risk Assessment

An attacker can remotely manipulate the JavaScript object prototype, potentially leading to privilege escalation, arbitrary code execution, or data integrity compromise in the application.

Recommendation

Immediately update @adonisjs/bodyparser to version 10.1.5 (for AdonisJS 10.x) or 11.0.3 (for AdonisJS 11.x).

Original NVD description (English source)

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.
