DescriptionCVE.org

OpenClaw before 2026.3.31 contains an authorization bypass vulnerability in Discord voice ingress that allows attackers to bypass channel and member allowlist restrictions. Attackers can exploit stale-role validation gaps and improper channel name validation to gain unauthorized access to restricted voice channels.

AnalysisAI

OpenClaw before version 2026.3.31 allows authenticated attackers to bypass authorization controls on Discord voice channels through exploitation of stale-role validation gaps and improper channel name validation, enabling unauthorized access to restricted voice channels that should be protected by member and channel allowlists. The vulnerability requires valid Discord credentials but enables privilege escalation within voice channel access controls. No public exploit code has been identified at the time of analysis.

Technical ContextAI

OpenClaw integrates with Discord's voice infrastructure to enforce access controls via channel and member allowlists. The vulnerability stems from CWE-862 (Missing Authorization) in the Discord voice ingress validation logic. The authorization bypass occurs at two critical points: role validation does not properly synchronize with stale Discord role assignments, and channel name validation fails to correctly match restricted channel identifiers. This allows authenticated users to circumvent the intended allowlist enforcement mechanisms that should restrict voice channel membership to explicitly authorized Discord members and channels.

RemediationAI

Update OpenClaw to version 2026.3.31 or later, which addresses both the stale-role validation gap and channel name validation flaws. The upstream fix is available via GitHub commit dba96e7507e0900f120e5e28e57755d69bf78759 (https://github.com/openclaw/openclaw/commit/dba96e7507e0900f120e5e28e57755d69bf78759). Until patching is feasible, temporarily disable Discord voice ingress functionality if not operationally critical, or implement network-level access controls to restrict OpenClaw instances to trusted Discord servers and role groups as an interim compensating control. Note that disabling voice ingress may impact legitimate use cases, so coordinate with stakeholders before deployment.
