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. Inspected the manifest, source prefetch path, emitted entrypoint, and runtime shim. The scanner's dependency-bridge hint is not supported by an active harmful behavior in the inspected code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-09T16:42:45.701Z - **Finished:** 2026-10-09T16:43:12.130Z - **Download time:** 1031 ms - **Static scan time:** 175 ms - **AI review time:** 25223 ms - **Total time:** 26429 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 attack was identified. The flagged bundle contains browser widget setup and a small runtime shim, with no confirmed harmful operation. - **Trigger:** Importing the package entrypoint or initializing a widget in a browser. - **Impact:** No concrete security impact beyond the package's captcha functionality was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T16:43:12.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint sets up the captcha widget and conditionally prefetches its detector through Prosopo modules. - **Rationale:** Inspected the manifest, source prefetch path, emitted entrypoint, and runtime shim. The scanner's dependency-bridge hint is not supported by an active harmful behavior in the inspected code. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies the package entrypoint and has no install lifecycle hook., The published entrypoint imports widget modules and the small Rolldown runtime shim; the shim only imports \`node:module\` and exports nothing., Detector prefetch is conditional on a site key and non-manual start mode, and uses Prosopo dependencies. ## Affected versions and remediation This report applies to @prosopo/procaptcha-bundle@4.4.8. - Review the evidence and your use of @prosopo/procaptcha-bundle@4.4.8 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** dist/index.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @prosopo/procaptcha-bundle; repositoryIdentity = captcha; dependency = @prosopo/procaptcha-common L5: import { WidgetThemeResolver } from "./util/widgetThemeResolver.js"; L6: import { getWindowCallback } from "@prosopo/procaptcha-common"; L7: import { PROCAPTCHA_START_EVENT, StartModeEnum } from "@prosopo/types"; ``` ### 5. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 6. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 65.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest identifies the package entrypoint and has no install lifecycle hook.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/index.js - **Public source:** [View source]() The published entrypoint imports widget modules and the small Rolldown runtime shim; the shim only imports \`node:module\` and exports nothing.
