## Overview

spaceship-prompt through 4.22.5 fails to sanitize control characters from project manifest version fields before rendering them in the zsh prompt. Attackers can embed ANSI/OSC escape sequences in version fields of package manifests to manipulate terminal output, rewrite window titles, or spoof displayed text when victims enter the directory.
