CVE-2026-76245
HighCVSS 7.1Summary
The stigmem 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. Fixed in 0.9.0a2.
Risk Assessment
Authenticated federation flows may be disrupted, leading to service unavailability and reliability issues in environments using peer authentication.
Recommendation
Upgrade stigmem-node to version 0.9.0a2 or later, which uses the canonical millisecond-based validation path.
