CVE-2026-53823

描述

### Summary Slack allowFrom could bind to mutable display names. In affected versions, a Slack 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 Slack 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 `2026.5.3`. ### Mitigations use stable Slack 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.
