Description
onefetch through 2.28.1 writes repository information field values to the terminal without removing control characters, allowing terminal escape sequence injection. Attackers can embed ANSI/OSC escape sequences in project manifest version and name fields to manipulate terminal output, rewrite window titles, hide text, or trigger emulator-specific behavior when victims run onefetch.
