CVE-2026-28460 Details
Description
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.
A vulnerability allowing allowlist bypass in OpenClaw has been identified in versions prior to 2026.2.22. This issue arises in the 'system.run' feature, where attackers can execute non-allowlisted commands by manipulating command substitution with shell line-continuation characters. By injecting a backslash followed by a newline and an opening parenthesis within double quotes, the shell interprets the line continuation as executable command substitution, bypassing security approvals and allowing unauthorized command execution.
Users can upgrade to OpenClaw version 2026.2.22 or later to address this vulnerability. As a temporary mitigation, set 'tools.exec.ask' to 'always' or 'tools.exec.security' to 'deny'.
