cve 2026 47300

The cve 2026 47300 tag covers Microsoft’s July 14 publication of an elevation-of-privilege vulnerability in ASP.NET Core. Current coverage focuses on the limited technical information in the initial Security Update Guide entry, including the absence of clearly stated affected versions, patch details, and an established attack path. For administrators, the advisory is a reason to inventory ASP.NET Core deployments and follow Microsoft’s related .NET servicing guidance as more information becomes available. This tag archive is intended for tracking updates to the advisory and practical context around assessing potential exposure, rather than drawing conclusions beyond what Microsoft’s public material currently confirms.
