CVE-2021-46703
In the IsolatedRazorEngine component of Antaris RazorEngine through 4.5.1-alpha001, an attacker can execute arbitrary .NET code in a sandboxed environment (if users can externally control template contents).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
