Assigner: VulnCheck

Description
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.

Executive Summary

CVE-2026-32923 is an authorization bypass vulnerability in OpenClaw versions before 2026.3.11. It occurs in the Discord guild reaction ingestion component, where the system fails to enforce allowlist checks for member users and roles.

Because of this flaw, non-allowlisted guild members can trigger reaction events that the system mistakenly accepts as trusted system events. This allows unauthorized injection of reaction text into downstream session contexts.

The vulnerability is classified under CWE-863 (Incorrect Authorization) and CWE-284 (Improper Access Control), with a medium severity CVSS score of 5.4.

Impact Analysis

This vulnerability allows unauthorized users who are not on the allowlist to inject reaction text into downstream session contexts by exploiting the Discord guild reaction ingestion process.

As a result, attackers can cause unauthorized reaction events to be processed as trusted system events, potentially leading to manipulation or corruption of session data.

The impact includes a low confidentiality and integrity impact, with no availability impact, but it still represents a moderate security risk due to improper authorization.

Mitigation Strategies

To mitigate the CVE-2026-32923 vulnerability, users should upgrade OpenClaw to version 2026.3.11 or later.

The fix in version 2026.3.11 applies the same users and roles allowlist enforcement to the Discord guild reaction ingress as is done for normal inbound guild messages, preventing unauthorized reaction events from being accepted as trusted system events.

Compliance Impact

The provided information does not specify how the CVE-2026-32923 vulnerability impacts compliance with common standards and regulations such as GDPR or HIPAA.
