CVE-2026-62199Network attack vector

Authenticated command execution via incomplete environment filtering

Published Jul 13, 2026 · Updated Jul 13, 2026

Command injection in OpenClaw before 2026.6.6 allows remote authenticated users to run host actions through crafted environment variables. The host exec environment filter passes interpreter startup variables that its denylist does not recognize into downstream processes. Exploitation requires the affected host-exec feature to be enabled and reachable from a lower-trust caller or configured input path; successful use crosses the caller's intended authorization boundary.
