Cursor and agent traffic can be intercepted locally and unpaid accounts can be presented as entitled. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.50.100 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. The explicit Cursor takeover feature redirects vendor and agent hosts to a local impersonation server. It forges paid membership state and weakens certificate validation to bypass vendor controls. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T00:44:48.529Z - **Finished:** 2026-09-08T00:46:24.309Z - **Download time:** 509 ms - **Static scan time:** 4174 ms - **AI review time:** 91096 ms - **Total time:** 95780 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The explicit Cursor takeover feature redirects vendor and agent hosts to a local impersonation server. It forges paid membership state and weakens certificate validation to bypass vendor controls. - **Trigger:** A user runs the Cursor command with takeover enabled; ordinary Cursor setup also attempts a privileged backend host block unless disabled. - **Impact:** Cursor and agent traffic can be intercepted locally and unpaid accounts can be presented as entitled. - **Evidence paths:** lib/setup.js, lib/hosts.js, lib/cursorbackend.js, lib/cursorcfg.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T00:46:24.309Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Host-file redirection, TLS impersonation, and membership forgery. - **Attack narrative:** When invoked, the package can use sudo to add loopback mappings for Cursor and agent backend hosts. In takeover mode it creates certificates for those vendor names, disables Cursor certificate checks, and serves an active paid membership response. It also modifies Cursor's local cached Stripe membership and subscription state. This redirects the editor to a package-controlled server and bypasses its subscription and model-selection controls. - **Rationale:** The package contains a concrete editor-control hijack and paid-tier bypass, not merely a user-configured proxy. Although it has no install hook, the explicit runtime path performs privileged host mutation, TLS impersonation, and membership forgery. - **Files touched:** /etc/hosts, ~/.openzoo/cursor-tls/cert.pem, ~/.openzoo/cursor-tls/key.pem, Cursor ItemTable - **Network endpoints:** api2.cursor.sh, \*.api5.cursor.sh, api.anthropic.com, api-staging.anthropic.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The Cursor command can redirect the editor and agent backend hosts to loopback, including takeover mode., The package creates certificates for Cursor and Anthropic service names and launches Cursor with certificate validation disabled., Its local server returns an active paid membership profile to bypass model gates., It writes Cursor's cached Stripe membership and subscription status as entitled and active., The file identifies Anthropic desktop inference hosts as impersonated and forwarded to a local proxy. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The hostile takeover path requires an explicit runtime command and privileged host-file modification. ## Affected versions and remediation This report applies to openzoo@0.50.100. - Avoid installing openzoo@0.50.100. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
