GHSA-9vp8-3hmv-8fgh: stigmem-node's federation peer registration lacked explicit out-of-band approval

May 29, 2026

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.
