upstream downstream

About this tag
The upstream downstream tag on WindowsForum.com covers the relationship between open-source projects and their downstream consumers, particularly in the context of security vulnerabilities. A key example is Chromium's CVE-2026-0901, a Blink engine bug that affects Microsoft Edge because Edge is built on Chromium. The tag explains how vulnerabilities are discovered upstream (in Chromium) and then fixed downstream (in Edge) when Microsoft incorporates the patched engine.

The tag is relevant for those tracking Chromium-based browser security and Microsoft's response to upstream flaws.
