CVE-2025-30089Public exploitNetwork attack vector

Terminal disruption via unsanitized message escape sequences

Published Mar 16, 2025 · Updated Mar 17, 2025

ANSI escape-sequence injection in boxdot gurk 0 through 0.6.3 allows remote attackers to disrupt the terminal via crafted Signal messages. The message drawing and name-resolution paths render received message text and display names without stripping terminal control codes. Exploitation requires delivery to a linked client; demonstrated effects include altered colors, cursor or title manipulation, cleared content, and an unusable terminal.
