Lifecycle Timeline
3Description
OpenClaw before 2026.3.11 contains an authorization bypass vulnerability in Discord guild reaction ingestion that fails to enforce member users and roles allowlist checks. Non-allowlisted guild members can trigger reaction events accepted as trusted system events, injecting reaction text into downstream session context.
Analysis
OpenClaw before version 2026.3.11 allows authenticated non-allowlisted Discord guild members to bypass authorization checks on reaction ingestion events, enabling them to inject arbitrary reaction text into downstream session context that is trusted as legitimate system events. This authentication-required authorization bypass affects all OpenClaw deployments integrating Discord guild reaction handling and has a CVSS score of 5.3 with confirmed patch availability.
