Description

<bytes::Bytes as axum_core::extract::FromRequest>::from_request would not, by default, set a limit for the size of the request body. That meant if a malicious peer would send a very large (or infinite) body your server might run out of memory and crash.

This also applies to these extractors which used Bytes::from_request internally:

  • axum::extract::Form
  • axum::extract::Json
  • String

The fix is also in axum-core 0.3.0.rc.2 but 0.3.0.rc.1 is vulnerable.

Because axum depends on axum-core it is vulnerable as well. The vulnerable versions of axum are <= 0.5.15 and 0.6.0.rc.1. axum >= 0.5.16 and >= 0.6.0.rc.2 does have the fix and are not vulnerable.

The patched versions will set a 2 MB limit by default.
