CVE-2026-73479Hinoki check available

Terminal manipulation via unfiltered marked path output

Published Aug 13, 2026 · Updated Aug 13, 2026

Terminal escape injection in dua-cli 2.41.1 and earlier allows local users to manipulate terminal state via crafted file names. After interactive mode releases ratatui's terminal control, main prints each marked path with path.display() without filtering control characters. A local user must place a crafted file in a scanned directory and induce an operator to mark it and quit; resulting OSC/CSI handling can spoof the title or alter clipboard contents, depending on the terminal emulator.
