Summary

Unauthenticated OIDC login in nebula-mesh allows unbounded memory allocation in github.com/forgekeep/nebula-mesh

Details

When OIDC is enabled, the login endpoint is reachable without authentication and is registered outside the rate-limited auth routes. Every request creates a fresh random OIDC state value and stores it in an in-memory map.

An unauthenticated remote client can grow the state storage, bounded by request throughput rather than by configured auth rate limits, potentially leading to a denial of service.
