Mitigating Controls (NIST 800-53 r5)AI
CM-11 directly mitigates the vulnerability by establishing and enforcing policies restricting user-installed software, preventing malicious workspace plugins from being loaded and bypassing trust gates.
CM-14 requires verification of digital signatures for software modules like plugins prior to installation or loading, blocking unsigned or tampered workspace plugin shadows.
SI-7 employs integrity verification mechanisms for software components during execution and loading, detecting and preventing unauthorized shadowing by malicious workspace plugins.
Security SummaryAI
CVE-2026-43571 is a plugin trust bypass vulnerability affecting OpenClaw versions before 2026.4.10. The issue arises during channel setup catalog lookups, which resolve workspace plugin shadows before bundled channel plugins, enabling malicious workspace plugins to bypass intended trust gates at setup-time plugin loading. Classified under CWE-829 (Inclusion of Functionality from Untrusted Control Sphere), it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low attack complexity, and significant impacts on confidentiality, integrity, and availability.
Attackers with low privileges (PR:L) can exploit this vulnerability over the network without user interaction. By crafting malicious workspace plugins, they bypass trust controls during plugin loading, potentially leading to high-impact compromise including unauthorized access to sensitive data (C:H), modification of system behavior (I:H), and disruption of services (A:H).
Mitigation details are available in official advisories and the patch commit. The GitHub security advisory (GHSA-82qx-6vj7-p8m2) and the fix in commit 1fede43b948df40ca8674511d4bd08d39f6c5837 address the issue, with upgrading to OpenClaw 2026.4.10 recommended. Additional analysis is provided in the VulnCheck advisory on untrusted workspace plugin shadow resolution in channel setup.
