🔬 Technical Analysis

Summary Matrix allowFrom could bind to mutable display names. In affected versions, a Matrix account able to change display name metadata could match a policy entry through mutable display metadata. 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.

Impact When the affected feature is enabled and reachable, this could receive agent access intended for another Matrix identity. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.
