CVE-2026-28391

OpenClaw < 2026.2.2 - Command Injection via cmd.exe Parsing Bypass in Allowlist Enforcement

State: Published
Severity: 9.2 Critical
Published: Mar 5, 2026
Updated: Mar 10, 2026
Reserved: Feb 27, 2026

Description

OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests (non-default configuration), allowing attackers to bypass command approval restrictions. Remote attackers can craft command strings with shell metacharacters like & or %...% to execute unapproved commands beyond the allowlisted operations.
