stigmem-node: Auth-disabled deployments may grant broad anonymous access outside loopback
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:
pip install --upgrade --pre stigmem-nodeIf developers install through the Stigmem meta-package instead, they should use the matching extra for their deployments, for example:
pip install --upgrade --pre 'stigmem[node]'Resources
