CVE-2026-28460 PUBLISHED

OpenClaw < 2026.2.22 - Allowlist Bypass via Shell Line-Continuation Command Substitution in system.run

Assigner: VulnCheck
Reserved: 27.02.2026 Published: 19.03.2026 Updated: 19.03.2026

OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in system.run that allows attackers to execute non-allowlisted commands by splitting command substitution using shell line-continuation characters. Attackers can bypass security analysis by injecting $\ followed by a newline and opening parenthesis inside double quotes, causing the shell to fold the line continuation into executable command substitution that circumvents approval boundaries.
