MEDIUM 4.3

DescriptionCVE.org

OpenClaw versions prior to 2026.2.25 fail to consistently apply sender-policy checks to reaction_* and pin_* non-message events before adding them to system-event context. Attackers can bypass configured DM policies and channel user allowlists to inject unauthorized reaction and pin events from restricted senders.

AnalysisAI

OpenClaw fails to consistently apply sender-policy checks to reaction and pin event handlers, allowing authenticated attackers to bypass configured direct message policies and channel user allowlists by injecting unauthorized events from restricted senders. The vulnerability affects OpenClaw versions prior to 2026.2.25, requires low privileges (authenticated user), and enables unauthorized event injection with moderate severity (CVSS 4.3). A patch is available from the vendor, and the vulnerability has been documented in the VulnCheck advisory and GitHub Security Advisory GHSA-rm2p-j3r7-4x4j.

Technical ContextAI

The vulnerability exists in OpenClaw's event handling system (cpe:2.3:a:openclaw:openclaw), a chat platform similar to Slack that manages collaborative communication through various event types. The root cause is classified under CWE-863 (Incorrect Authorization), where sender-policy validation mechanisms designed to enforce DM policies and channel user allowlists are not consistently applied to non-message events specifically reaction_* and pin_* event types. These events are processed and added to the system-event context without proper authorization checks, creating a gap where the authentication model exists but authorization enforcement is inconsistent across different event categories. The underlying issue is a failure to validate event source permissions before context mutation.

RemediationAI

Upgrade OpenClaw to version 2026.2.25 or later to apply the sender-policy validation fixes implemented in commits aedf62ac7e669a89c7b295201bf6537dc6b12e0e and 75dfb71e4e8b7c2feba5a8ca662f92ea840e0147. Organizations unable to immediately patch should review and restrict who can perform reaction and pin operations in sensitive channels, enforce channel membership controls, and audit recent reaction and pin events for unauthorized sources.
