EPSS · scored 2026-10-27

OpenClaw versions 2026.2.13 through 2026.3.24 contain an ANSI escape sequence injection vulnerability in approval prompts that allows attackers to spoof terminal output. Untrusted tool metadata can carry ANSI control sequences into approval prompts and permission logs, enabling attackers to manipulate displayed information through malicious tool titles.

    ## 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`
