MediumMetricsAV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N
Name of the Vulnerable Software and Affected Versions
OpenClaw versions prior to 2026.4.24
Description
An authorization bypass exists in the MCP loopback feature. This allows non-owner callers to circumvent owner-only tool policies and before-tool-call hooks. When the feature is enabled and reachable, attackers can use the affected loopback path to invoke owner-only behavior and execute restricted tools.
Recommendations
Update to version 2026.4.24.
As a temporary workaround, disable the MCP loopback feature to prevent unauthorized execution of restricted tools.
