CVE-2026-30278Network attack vector

Code execution via unrestricted file import paths

Published Mar 31, 2026 · Updated Mar 31, 2026

Arbitrary file overwrite in FLY is FUN Aviation Navigation 35.33 allows remote attackers to replace internal files through file import. The file import process fails to confine attacker-controlled paths to its intended storage area, allowing imported content to replace critical application files. No authentication or user interaction is required; successful exploitation exposes stored information or executes code in the app context.
