CVE

GHSA-9vp8-3hmv-8fgh

stigmem-node's federation peer registration lacked explicit out-of-band approval

Impact

Federation peer registration accepted peer key material during registration without a separate administrator approval step based on an out-of-band fingerprint check. Impacted deployments are nodes that accept federation peer registration across a network where initial registration could be intercepted or misdirected.

Patches

Patched in 0.9.0a2. Peer registration now uses a pending approval flow, and peer tokens are not accepted until an administrator approves the peer using the expected fingerprint.

Workarounds

Before upgrading, restrict peer registration endpoints to trusted administrative networks and verify peer public-key fingerprints out of band before allowing federation traffic.

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 deployments, for example:

pip install --upgrade --pre 'stigmem[node]'
