CVE-2026-28391
OpenClaw < 2026.2.2 - Command Injection via cmd.exe Parsing Bypass in Allowlist Enforcement
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.
