Package content can influence Cursor agent behavior across projects without an interactive consent step. - **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:** 0.1.107 - **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. Installing the package automatically changes the user's global Cursor AI instruction surface. It copies and rewrites skills so they are applied globally, and deletes selected prior skill folders. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T04:52:09.992Z - **Finished:** 2026-09-11T04:53:41.028Z - **Download time:** 1260 ms - **Static scan time:** 11917 ms - **AI review time:** 77855 ms - **Total time:** 91036 ms The recorded confidence comes from the underlying analysis.

It copies and rewrites skills so they are applied globally, and deletes selected prior skill folders. - **Trigger:** npm install or npx installation of the package - **Impact:** Package content can influence Cursor agent behavior across projects without an interactive consent step. - **Evidence paths:** package.json, scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:53:41.028Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes global always-applied Cursor skills - **Attack narrative:** The registry install lifecycle launches the package installer automatically. For consumer installs, it writes shipped skills beneath the user's global Cursor configuration, overwrites package-managed copies, rewrites their front matter to make them always apply, and removes stale or legacy skill directories. This is an unconsented postinstall mutation of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle hook modifies a global Cursor instruction directory and activates installed instructions globally. This satisfies the install-hook policy for a broad AI-agent control-surface mutation despite the opt-out and absence of network activity. - **Files touched:** scripts/install-cursor-skills.mjs, dist/internal/install-cursor-skills.js, ~/.cursor/skills/agentsdk/, ~/.cursor/skills/agentkit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook runs a package script automatically during installation., The installer copies shipped content into the user's global Cursor skills directory and overwrites existing package-owned skill folders., Installed skill files are rewritten to set alwaysApply true, making their instructions global Cursor rules., The install path also removes stale folders and the legacy agentkit namespace without an interactive prompt., The postinstall launcher imports and invokes the Cursor-skill synchronization routine. - **Evidence against:** The installer has an environment-variable opt-out and limits its target to Cursor skill directories., The inspected install path contains no network request or credential collection. ## Affected versions and remediation This report applies to @cursor/july@0.1.107. - Avoid installing @cursor/july@0.1.107. 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.
