CVE-2026-35651 Details
Description
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.
A vulnerability allowing ANSI escape sequence injection has been identified in OpenClaw versions 2026.2.13 prior to 2026.3.25. This issue resides in the approval prompts of the ACP CLI, where untrusted tool metadata can introduce ANSI control sequences. Such sequences can manipulate terminal output, potentially leading to spoofed information in permission logs and approval prompts. The vulnerability arises because the application did not properly sanitize tool titles before they were displayed or logged.
Users can upgrade to OpenClaw version 2026.3.25 or later, where this vulnerability has been patched.
