downstream ingestion

About this tag
The downstream ingestion tag on WindowsForum.com covers how Microsoft Edge and other Chromium-based browsers incorporate upstream Chromium security fixes. Discussions explain that when Chromium patches a vulnerability, Microsoft must verify that the fix has been ingested into Edge builds and then publish that information in the Security Update Guide. Topics include specific CVEs like CVE-2026-0908 and CVE-2025-10201, the role of the Chromium project as an upstream source, and the process of tracking which builds contain the fix. The tag is relevant for IT administrators and users who need to understand when a downstream browser build is no longer vulnerable after an upstream patch.
