CVE-2026-28391 PUBLISHED

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

Assigner: VulnCheck
Reserved: 27.02.2026 Published: 05.03.2026 Updated: 05.03.2026

OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests, 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.
