CVE-2023-26314
The mono package before 6.8.0.105+dfsg-3.3 for Debian allows arbitrary code execution because the application/x-ms-dos-executable MIME type is associated with an un-sandboxed Mono CLR interpreter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
