GHSA-4hmj-39m8-jwc7
Summary OpenClaw has ACP CLI approval prompt ANSI escape sequence injection ## Summary ACP CLI approval prompt ANSI escape sequence injection ## Affected Packages / Versions - Package: `openclaw` - Affected versions: `>= 2026.2.13, <= 2026.3.24` - First patched version: `2026.3.25` - Latest published npm version at verification time: `2026.3.24` ## Details ACP tool titles could previously carry ANSI control sequences into approval prompts and permission logs, letting untrusted tool metadata spoof terminal output. Commit `464e2c10a5edceb380d815adb6ff56e1a4c50f60` sanitizes tool titles at the source and broadens ANSI stripping to full CSI sequences. Verified vulnerable on tag `v2026.3.24` and fixed on `main` by commit `464e2c10a5edceb380d815adb6ff56e1a4c50f60`. ## Fix Commit(s) - `464e2c10a5edceb380d815adb6ff56e1a4c50f60`
