CVE-2026-101880
OpenClaw Windows Node before 2026.7.1 contains an incorrect authorization vulnerability in the system.run exec-approval policy where ExecShellWrapperParser fails to split commands on pipe operators or extract command substitutions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
OpenClaw Windows Node before 2026.7.1 contains an incorrect authorization vulnerability in the system.run exec-approval policy where ExecShellWrapperParser fails to split commands on pipe operators or extract command substitutions. Connected gateways or agents can bypass approval rules by placing denied commands behind allowed prefixes using pipe operators or command substitution syntax, achieving arbitrary command execution on Windows hosts.
