DescriptionNVD
OpenClaw before 2026.3.31 contains a fail-open vulnerability in the plugin installation flow where security scan failures do not block installation. Attackers can exploit scan failures to install untrusted plugins when operators proceed despite visible scan warnings.
AnalysisAI
OpenClaw before version 2026.3.31 fails to block plugin installation when security scans detect threats, allowing authenticated users to install malicious plugins by ignoring visible scan warnings. The vulnerability requires user interaction (UI:P) and authenticated access (PR:L), but enables installation of untrusted code with moderate integrity impact when exploited.
