Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection shows a legitimate Cursor agent SDK: network, env, filesystem, and agent tool primitives are tied to explicit SDK calls and local/cloud agent functionality. There is no consumer install-time execution, foreign AI-agent control-surface write, persistence, credential harvesting, or command-output exfiltration path established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-07-05T02:23:58.658Z - **Finished:** 2026-07-05T02:24:53.932Z - **Download time:** 763 ms - **Static scan time:** 6185 ms - **AI review time:** 48325 ms - **Total time:** 55274 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:** No confirmed malicious attack surface was found. The package is an agent SDK with user-invoked cloud/local runtime capabilities and package-aligned local state storage. - **Trigger:** User imports the SDK and calls Agent/Cursor APIs. - **Impact:** Can contact Cursor cloud and maintain local run/checkpoint state when the application opts in; no unconsented lifecycle mutation or credential harvesting found. - **Evidence paths:** package.json, README.md, dist/cjs/index.js, dist/esm/index.js, dist/esm/642.js, dist/esm/986.js, dist/esm/400.js, dist/esm/sqlite.js, dist/cjs/sqlite.js - **Review source:** ai\_review - **Reviewed:** 2026-07-05T02:24:53.932Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked Cursor agent SDK operations - **Rationale:** Static inspection shows a legitimate Cursor agent SDK: network, env, filesystem, and agent tool primitives are tied to explicit SDK calls and local/cloud agent functionality. There is no consumer install-time execution, foreign AI-agent control-surface write, persistence, credential harvesting, or command-output exfiltration path established. - **Files touched:** package.json, README.md, dist/cjs/index.js, dist/esm/index.js, dist/esm/642.js, dist/esm/986.js, dist/esm/400.js, dist/esm/sqlite.js - **Network endpoints:** https://cursor.com ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has only prepublishOnly; no install/postinstall hook for consumers., Entrypoints are SDK exports in dist/cjs/index.js and dist/esm/index.js, not import-time payload launchers., Cloud code in dist/esm/642.js requires explicit apiKey/CURSOR\_API\_KEY and user API calls for cloud agents., Runtime writes are local agent state files such as agents.ndjson, runs.ndjson, run\_events.ndjson, checkpoints.ndjson under caller-selected/default state root., MCP servers, envVars, artifacts, and prompts are user-supplied SDK options, not harvested automatically., dist/esm/sqlite.js child\_process/native-loading signals are bundled sqlite/local-runtime support, not lifecycle persistence or exfiltration. ## Affected versions and remediation This report applies to @cursor/sdk@1.0.22. - Review the evidence and your use of @cursor/sdk@1.0.22 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
