Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. An authenticated marketplace install can write server-provided content to a server-provided resolved path. The path is not constrained to the project or an extension directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-04T16:12:10.457Z - **Finished:** 2026-09-04T16:13:31.384Z - **Download time:** 506 ms - **Static scan time:** 970 ms - **AI review time:** 79450 ms - **Total time:** 80927 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:** An authenticated marketplace install can write server-provided content to a server-provided resolved path. The path is not constrained to the project or an extension directory. - **Trigger:** The user runs iobend install for a marketplace item while authenticated. - **Impact:** A compromised or malicious marketplace response can overwrite arbitrary user-writable files and potentially establish later code execution. - **Evidence paths:** src/commands/install/index.js, src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T16:13:31.384Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unchecked remote path and content write - **Rationale:** This is a concrete remote arbitrary-file-write supply-chain vulnerability in a user-invoked command, not an automatic install-time attack. The absence of lifecycle hooks and explicit trigger support a warning rather than a publish block. - **Network endpoints:** https://iobend.com/api/cli/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The authenticated marketplace installer accepts remote file paths and writes supplied content without restricting the destination., The claimed signature check only accepts a successful server response; it does not verify a downloaded artifact or the returned file contents., The command is reachable through the public iobend install command. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The vulnerable write path requires an explicit user install command and an existing token., No automatic credential harvesting or import-time network activity was found. ## Affected versions and remediation This report applies to iobend@2.6.1. - Review the evidence and your use of iobend@2.6.1 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.
