Claude HUD through 0.0.12, patched in commit 234d9aa, constructs OSC 8 terminal hyperlink escape sequences using raw cwd and branchUrl values without stripping control characters or encoding embedded values, allowing attackers to inject arbitrary ANSI codes into terminal sessions. Attackers can embed ESC+backslash sequences in the current working directory or branch URL to execute malicious ANSI codes including text color changes, forged prompts, and OSC 52 clipboard writes, or trigger outbound HTTP requests to attacker-controlled remotes when hyperlinks are clicked.
AnalysisAI
Terminal injection in Claude HUD through version 0.0.12 allows an attacker who controls a Git branch name or working directory path to embed arbitrary ANSI escape sequences into terminal sessions via unsanitized OSC 8 hyperlink construction. When a user runs Claude HUD in an affected terminal emulator and clicks a rendered project or branch hyperlink, injected sequences—including OSC 52 clipboard writes and forged prompts—are processed by the terminal. …
