Title

OpenClaw < 2026.5.7 - Privilege Escalation via Mutable Discord Display Names in allowFrom

Summary

OpenClaw before 2026.5.7 contains a privilege escalation vulnerability where the allowFrom feature improperly validates Discord account identity using mutable display names instead of immutable user IDs. Attackers with Discord accounts can change their display name to match a policy entry and gain unauthorized agent access intended for another Discord identity.

Severity

GHSA-CW4Q-GQG5-G38H

Vulnerability from github – Published: 2026-06-18 20:36 – Updated: 2026-06-18 20:36

Summary

OpenClaw: Discord allowFrom could bind to mutable display names

Details

Summary

Discord allowFrom could bind to mutable display names. In affected versions, a Discord account able to change display or global 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 Discord 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 Discord 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.
