# GHSA-fp6w-8wpg-74g5: stigmem-node: Auth-disabled deployments may grant broad anonymous access outside loopback

## Affected packages

- PyPI `stigmem-node` < 0.9.0a2 → fixed: 0.9.0a2

## Details

Impact Stigmem nodes configured with authentication disabled could grant the anonymous identity broad read/write/federation capabilities if exposed outside a loopback-only local development environment. Impacted users are operators who intentionally disabled authentication while binding the node to a non-loopback URL. Patches Patched in 0.9.0a2. The node now refuses unauthenticated operation outside loopback-only local development. Workarounds Before upgrading, keep authentication enabled for all non-local deployments and do not expose nodes with authentication disabled to untrusted networks. Upgrade Upgrade to the patched release: If developers install through the Stigmem meta-package instead, they should use the matching extra for their deployments, for example: Resources - Release: https://github.com/eidetic-labs/stigmem/releases/tag/v0.9.0a2 - Changelog: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/CHANGELOG.md#L14-L35 - Security policy and posture: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/SECURITY.md
