Summary

Current Maintainer Triage

• Status: open
• Normalized severity: medium
• Assessment: v2026.3.28 still parses Teams JSON after only a Bearer-prefix gate and before real JWT validation, and the auth-before-parse fix is not yet shipped.

• Latest published npm version: 2026.3.31
• Vulnerable version range: <=2026.3.28
