TL;DR

Affected versions of this package are vulnerable because the OTel exporter transmits the raw signing key in the Authorization Bearer header, instead of a hashed version. This exposes credentials or keys to potential disclosure through logs, proxies, or intermediaries that may have access to request headers.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and use the OTel exporter or extended traces functionality that sends the signing key in outgoing Authorization headers.

Background info

inngest is vulnerable to Insertion of Sensitive Information Into Sent Data in versions 0.0.1 - 4.2.4.

How to fix this

Upgrade the inngest library to version 4.2.5 or later.
