Improper link resolution before file access ('link following') in .NET allows an authorized attacker to elevate privileges locally.
CVE-2025-55247
This high-severity CVE scores 7.3 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 57% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
