OpenClaw versions before 2026.6.6 contain an environment variable filtering vulnerability in host exec that fails to properly sanitize rustup startup variables. Attackers with lower-trust caller access or configured input paths can execute or persist actions beyond their intended authorization level.
The CVSS severity warrants an early asset and exposure review.
