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.
Patched Versions
The first stable patched version is
2026.5.7.Mitigations
use stable Matrix user IDs in allowlists until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
Fix
Authentication Bypass by Spoofing
