CVE-2026-53811: OpenClaw: Matrix allowFrom could bind to mutable display names

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.
