GHSA-f397-5vjw-v2c2
Summary OpenClaw: Shell inline-command parsing could miss an allowlist check Shell inline-command parsing could miss an allowlist check. In affected versions, a command request using shell inline-command forms could route an inline command through a parser case that did not receive the expected allowlist decision. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
