github.com/controlplaneio-fluxcd/flux-operator is vulnerable to Denial of Service (DoS)
75
High Risk
This Affects:
github.com/controlplaneio-fluxcd/flux-operatorTL;DR
The web UI does not limit the size of request bodies on POST, PUT, or PATCH. A remote attacker can send an oversized body to these endpoints, causing the server to buffer unbounded data and leading to high memory use or denial of service. The fix adds a middleware that wraps the request body with http.MaxBytesReader (1MB limit) for those methods.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
