stigmem (pip package stigmem-node) version 0.9.0a1 contains a timestamp-handling mismatch in federation peer-token validation that can cause valid peer tokens to be incorrectly treated as expired. This affects the availability and reliability of authenticated federation flows on nodes using federation peer authentication paths. The issue is fixed in 0.9.0a2, which uses the canonical millisecond-based validation path.
CVE-2026-76245
This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (13th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
