Description
Fixed in OpenClaw 2026.3.24, the current shipping release.
Summary
The shared /allowlist command persists channel authorization config through writeConfigFile(...) but does not re-validate gateway client scopes for internal gateway callers. Because chat.send is intentionally reachable to operator.write callers and still creates a generic command-authorized internal context, an authenticated write-scoped gateway client can indirectly mutate channel allowFrom and groupAllowFrom policy that direct config.patch correctly reserves to operator.admin.
This is not just a generic code smell. The current code already shows the intended boundary by adding sink-side internal admin checks to shared /config and /plugins writes, but /allowlist was left behind.
Details
The gateway's documented scope split is clear:
chat.sendis a write-scoped action.- direct config mutation is an admin-scoped action.
The vulnerable path is:
- A gateway client authenticates with
operator.write. - The client calls
chat.send, which is intentionally allowed for that scope. chat.sendbuilds an internal message context withCommandAuthorized: trueand carriesGatewayClientScopesinto the reply pipeline.resolveCommandAuthorization(...)converts that internal message intoisAuthorizedSender=truein the common case where no strictercommands.allowFromoverride is configured./allowlist add|removeaccepts that generic command authorization and proceeds into its config-backed edit path.- The handler clones the parsed config, calls
plugin.allowlist.applyConfigEdit(...), validates the result, and persists it withwriteConfigFile(validated.config). - No sink-side check requires
operator.adminbefore the persistent write occurs.
That creates a direct control-plane mismatch:
config.patchrejects the same caller withmissing scope: operator.admin./allowlist add dm ...or/allowlist add group ...reached throughchat.sendcan still rewrite channel authorization state.
Impact
- A gateway client intentionally limited to
operator.writecan persist first-party channel authorization policy. - The caller can widen DM or group allowlists for channels using the shared
/allowlistplumbing. - This weakens the repo's documented control-plane privilege split between ordinary write actions and admin-only persistent authorization mutation.
Remediation
1) Add the Missing Sink-Side Internal Admin Check to /allowlist
Mirror the existing hardened pattern from /config and /plugins.
Before any config-backed /allowlist add|remove write, require:
operator.adminfor internal gateway channels
This should happen before plugin.allowlist.applyConfigEdit(...) and before writeConfigFile(...).
2) Keep Pairing-Store and Config-Write Policy Checks, but Do Not Treat Them as Scope Enforcement
configWrites policy and pairing-store behavior are useful secondary controls, but they do not replace the missing privilege check between operator.write and operator.admin.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-269: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How to prevent it
- Architecture and Design, Operation: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Architecture and Design: Follow the principle of least privilege when assigning access rights to entities in a software system.
- Architecture and Design: Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
