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-node

If 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]'
