CVE-2025-64494Network attack vector

Terminal output spoofing via unsanitized stored fields

Published Nov 8, 2025 · Updated Nov 8, 2025

Control-sequence injection in Charmbracelet Soft Serve 0.10.0 and earlier allows remote authenticated users to spoof terminal output. The SSH commands render unsanitized repository descriptions, project names, commit authors and messages, token names, and webhook URLs as terminal text. A low-privileged user must first store crafted ANSI sequences and another user must view affected output; resulting terminal content can display false alerts or conceal genuine text.
