Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected entrypoints delegate runtime behavior to dependencies whose source is unresolved, including @kubb/core, which is imported by both the public API and CLI. No attack was confirmed, but the unresolved runtime source prevents a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-25T17:49:35.802Z - **Finished:** 2026-10-25T17:50:04.416Z - **Download time:** 1283 ms - **Static scan time:** 36 ms - **AI review time:** 27294 ms - **Total time:** 28614 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 attack surface was identified in the inspected entrypoints. Runtime behavior remains unresolved because the package imports dependencies whose source was unavailable in this snapshot. - **Trigger:** Importing the public runtime entrypoint or running the kubb command. - **Impact:** No attack impact was confirmed; behavior in unavailable dependency source could not be assessed. - **Evidence paths:** package.json, bin/kubb.js, dist/index.js, .lpm-dependency-evidence-acf98c5a-9e1a-4511-98f8-8eae3d83ba27/0/npm-linux/dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-25T17:50:04.416Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoints delegate runtime work to @kubb/core and @kubb/cli, whose full behavior was not resolved here. - **Rationale:** The inspected entrypoints delegate runtime behavior to dependencies whose source is unresolved, including @kubb/core, which is imported by both the public API and CLI. No attack was confirmed, but the unresolved runtime source prevents a clean verdict. ### Review decision - **Verdict:** Manual Review - **Confidence:** 84.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package depends on several Kubb runtime packages at version 5.14.1, including @kubb/core., The command line entrypoint passes user-supplied arguments to @kubb/cli., The public runtime entrypoint imports createKubb from @kubb/core., The inspected CLI source also imports multiple runtime functions from @kubb/core. - **Evidence against:** No concrete attack behavior was established in the inspected entrypoints; the imported @kubb/core implementation and other dependencies with unresolved source remain unassessed. ## Affected versions and remediation This report applies to kubb@5.14.1. - Review the evidence and your use of kubb@5.14.1 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.
