Sources and claim methodology

Upstream source description

dua-cli fails to filter terminal escape sequences when printing marked file paths after exiting the TUI interface. Attackers can craft file names containing OSC/CSI escape sequences that are interpreted by the terminal emulator when printed, enabling title spoofing, clipboard manipulation, or other escape-sequence attacks.
