Impact
The flaw is an improper link resolution before file access in .NET, allowing an authorized attacker to elevate privileges locally. This is an elevation of privilege vulnerability categorized as CWE-59, which can grant higher local rights by following symbolic or hard links during file operations.
Affected Systems
Affected products include Microsoft .NET versions 10.0, 11.0, 8.0, and 9.0, as well as Microsoft Visual Studio 2022 version 17.14 and Microsoft Visual Studio 2026 version 18.10. No additional sub‑versions are listed.
Risk and Exploitability
The CVSS score of 7.8 indicates a high severity with a local attack vector. The EPSS score is not available, and the vulnerability is not listed in CISA’s KEV catalog, suggesting no known widespread exploitation yet. An attacker who already authenticates to the affected system can exploit the flaw by manipulating link resolution to gain elevated local privileges. The vulnerability requires local or user‑authenticated access and does not appear to be exploitable remotely. Consequently, the risk is significant for systems where users run .NET applications with elevated privileges.
