Summary

OpenClaw has ACP CLI approval prompt ANSI escape sequence injection

Details

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.

CVE-2026-35651 (GCVE-0-2026-35651)

Vulnerability from cvelistv5 – Published: 2026-04-10 16:03 – Updated: 2026-04-14 14:29 X_Open Source

Title

OpenClaw 2026.2.13 < 2026.3.25 - ANSI Escape Sequence Injection in Approval Prompt

Summary

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.
