# Coraza: Resource exhaustion via deferred file handle accumulation in multipart body processor in github.com/corazawaf/coraza

Coraza is a Go web application firewall library; versions 3.0.0 through 3.8.0 (exclusive) accumulate deferred file handles while processing multipart request bodies. An attacker who sends crafted multipart requests can exhaust the server's resources.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- go:github.com/corazawaf/coraza affected all versions fixed ?
- go:github.com/corazawaf/coraza/v2 affected all versions fixed ?
- go:github.com/corazawaf/coraza/v3 affected >= 3.0.0, < 3.8.0 fixed 3.8.0

## How to check

Run `go list -m github.com/corazawaf/coraza/v3` in the project and check whether the version is >= 3.0.0 and < 3.8.0.

## Fix

Upgrade github.com/corazawaf/coraza/v3 to 3.8.0 or later.
