CVE-2026-73480

Terminal state manipulation via unsanitized quit output

Published Aug 13, 2026 · Updated Aug 13, 2026

Terminal injection in gdu allows local users to alter terminal state through crafted file or directory names printed after TUI exit. The doQuit and printMarkedPaths paths write currentDirPath and markedPaths directly to os.Stdout after tview protection ends, without stripping control characters. Exploitation requires a local user to run the TUI, enter or mark an attacker-named filesystem entry, and quit; effects depend on the terminal emulator and include title or clipboard manipulation.
