CVE-2026-41382: OpenClaw Auth Bypass Vulnerability

CVE-2026-41382 Overview

OpenClaw before version 2026.3.31 contains an authorization bypass vulnerability in the Discord voice ingress component that allows attackers to bypass channel and member allowlist restrictions. By exploiting stale-role validation gaps and improper channel name validation, attackers can gain unauthorized access to restricted voice channels. This vulnerability is classified under CWE-862 (Missing Authorization).

Critical Impact
Unauthorized access to restricted Discord voice channels through allowlist bypass, potentially exposing sensitive communications and voice interactions.

Affected Products

OpenClaw versions prior to 2026.3.31
OpenClaw Discord voice ingress component
OpenClaw plugin-sdk authorization modules

Technical Details for CVE-2026-41382

Vulnerability Analysis

This authorization bypass vulnerability exists in OpenClaw's Discord voice ingress functionality. The flaw stems from inadequate validation of user roles and channel permissions when processing voice channel access requests. When a user attempts to join a restricted voice channel, the system fails to properly verify current role assignments and channel allowlist configurations, allowing unauthorized access through stale role validation and improper channel name matching.

The vulnerability allows authenticated users with low privileges to bypass access controls intended to restrict voice channel participation. The attack requires network access and low-privilege authentication, though it does require specific conditions to be present (stale role data or misconfigured channel names).

Root Cause

The root cause of CVE-2026-41382 is missing authorization checks in the Discord voice ingress path. Specifically, the voice command handler in extensions/discord/src/voice/command.ts did not properly gate voice ingress through the allowlist authorization functions. The vulnerable code path allowed direct access to voice channels without invoking the necessary authorization checks including isDiscordGroupAllowedByPolicy, resolveDiscordOwnerAccess, resolveDiscordChannelConfigWithFallback, resolveDiscordGuildEntry, and resolveDiscordMemberAccessState functions.

Attack Vector

The attack exploits the network-accessible Discord voice ingress endpoint. An authenticated attacker with a low-privilege Discord account can leverage stale role validation gaps where role revocations are not immediately reflected in access decisions. Additionally, improper channel name validation allows bypassing restrictions through crafted channel name patterns. The attack does not require user interaction and can be executed remotely against vulnerable OpenClaw instances.

The security patch introduces a dedicated authorizeDiscordVoiceIngress function in extensions/discord/src/voice/access.ts that properly validates:

typescript

+import type { Guild } from "@buape/carbon";
+import { resolveCommandAuthorizedFromAuthorizers } from "openclaw/plugin-sdk/command-auth";
+import { resolveOpenProviderRuntimeGroupPolicy } from "openclaw/plugin-sdk/config-runtime";
+import type { OpenClawConfig } from "openclaw/plugin-sdk/config-runtime";
+import type { DiscordAccountConfig } from "openclaw/plugin-sdk/config-runtime";
+import {
+  isDiscordGroupAllowedByPolicy,
+  resolveDiscordChannelConfigWithFallback,
+  resolveDiscordGuildEntry,
+  resolveDiscordMemberAccessState,
+  resolveDiscordOwnerAccess,
+} from "../monitor/allow-list.js";
+
+export async function authorizeDiscordVoiceIngress(params: {
+  cfg: OpenClawConfig;
+  discordConfig: DiscordAccountConfig;
+  groupPolicy?: "open" | "disabled" | "allowlist";
+  useAccessGroups?: boolean;
+  guild?: Guild<true> | Guild | null;
+  guildName?: string;
+  guildId: string;
+  channelId: string;
+  channelName?: string;
+  channelSlug: string;
+  parentId?: string;
+  parentName?: string;
+  parentSlug?: string;
+  scope?: "channel" | "thread";
+  channelLabel?: string;
+  memberRoleIds: string[];

Detection Methods for CVE-2026-41382

Indicators of Compromise

Unexpected voice channel joins from users without proper role assignments
Access logs showing voice ingress to restricted channels by non-allowlisted members
Discord audit logs revealing voice channel access from revoked or expired roles
Anomalous patterns of voice channel access bypassing configured allowlist policies

Detection Strategies

Monitor OpenClaw voice ingress logs for access attempts that bypass allowlist checks
Implement alerting on voice channel joins where the user's role cache may be stale
Review Discord server audit logs for unauthorized voice channel participation
Deploy application-level logging to track authorization decision paths in voice access

Monitoring Recommendations

Enable verbose logging for the extensions/discord/src/voice/ module components
Configure alerts for failed authorization attempts followed by successful voice joins
Monitor for discrepancies between Discord role assignments and OpenClaw cached role data
Implement periodic role synchronization health checks between Discord and OpenClaw

How to Mitigate CVE-2026-41382

Immediate Actions Required

Upgrade OpenClaw to version 2026.3.31 or later immediately
Review voice channel access logs for any unauthorized access patterns
Audit current allowlist configurations for Discord voice channels
Verify role synchronization between Discord and OpenClaw is functioning correctly
Temporarily restrict voice channel access to high-trust roles if patching is delayed

Patch Information

The vulnerability is addressed in OpenClaw version 2026.3.31. The fix introduces the authorizeDiscordVoiceIngress function that properly validates channel allowlists, member access states, and group policies before permitting voice ingress. The patch is available via the GitHub Commit Update. Additional details are available in the GitHub Security Advisory.

Workarounds

Set groupPolicy to disabled for sensitive voice channels until patching is complete
Implement manual role verification procedures for restricted voice channel access
Use Discord's native permission system as an additional layer of access control
Restrict voice channel creation to administrators only

bash

# Configuration example - Restrict voice ingress policy
# In your OpenClaw configuration file, set strict allowlist mode:
openclaw config set discord.voice.groupPolicy "allowlist"
openclaw config set discord.voice.strictRoleValidation true
openclaw config reload
