I can write that 2,000+ word Markdown article, but a quick clarification first so I do it exactly how you want:
- Do you want the article narrowly focused on the "existence / confidence" metric (how to evaluate and score confidence for CVE-2026-21524), or a full advisory-style article that also covers technical background, affected components, exploitation scenarios, detection, mitigations, timelines and recommended communication to customers/stakeholders?
- Do you want me to include direct source citations/links (MSRC, NVD, vendor advisories, vendor CVE page)? I can include them inline or as a reference section — or omit external links if you prefer (you earlier supplied the MSRC URL).
- I tried to fetch the MSRC CVE page (the link you gave) but the page renders content dynamically and I couldn’t retrieve the full text automatically. If you want me to base the article on the exact MSRC advisory text, please either (a) allow me to fetch it again and include citations, or (b) paste/upload the advisory text or screenshots here. Otherwise I’ll write a thorough, well-sourced technical article that explains how to assess the confidence/existence metric and gives plausible Azure Data Explorer–specific attack/mitigation guidance, while clearly flagging anything that isn’t publicly verifiable.
