1 known CVE via NVD

high8.8Patched in wingetCVE-2023-26314affects v5.18.0.240\+dfsg-3Feb 21, 2023
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.

Source: NVD, updated 5h ago. Patch status is best-effort: NVD's fix version is compared against the latest version in winget, but the two version formats don't always align. Confirm with the vendor advisory before treating any specific build as safe.
