CVE-2026-53829 Details
Description
OpenClaw before 2026.5.18 contains an approval display truncation vulnerability allowing authenticated users to hide command suffixes from approvers. Attackers can submit oversized exec commands with benign prefixes and malicious suffixes to execute unauthorized operations after approval.
A vulnerability exists in OpenClaw versions prior to 2026.5.18, where the approval display for exec commands is truncated. This allows authenticated users to obscure command suffixes from approvers. Attackers can exploit this by sending oversized exec commands that appear benign but contain malicious suffixes, enabling unauthorized operations to be executed after approval.
Users are advised to upgrade to OpenClaw version 2026.5.18 or later. Before upgrading, it is recommended to avoid approving unusually long exec commands and to limit approval capabilities to trusted operators.
