The change updates shared “source of truth” build/CVE data where correctness depends on external validation and impacts multiple downstream scripts.
Pull request overview
Updates the repository’s Exchange build/version metadata and HealthChecker CVE mappings to include the September 2026 Security Update (SU), ensuring “latest SU” detection and vulnerability reporting stay current.
Changes:
- Switches “latest SU build” detection from
Aug26SUtoSep26SUfor Exchange SE RTM, Exchange 2019 CU14/CU15, and Exchange 2016 CU23. - Adds
Sep26SUbuild numbers to the Exchange build dictionary for Exchange 2016 (15.1), Exchange 2019 (CU14/CU15), and Exchange SE RTM. - Adds a
Sep26SUCVE mapping entry and updates the Exchange SE HealthChecker test expectation accordingly.
