Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 10 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 4.1.59 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The manifest has no install lifecycle hook, and the inspected entrypoint’s imports and conditional prefetch align with a CAPTCHA widget. The scanner’s runtime bridge hint is not evidence of malicious behavior in the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T16:43:08.737Z - **Finished:** 2026-10-09T16:43:30.270Z - **Download time:** 1281 ms - **Static scan time:** 140 ms - **AI review time:** 20112 ms - **Total time:** 21533 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 in the inspected entrypoint or manifest. The package exposes a CAPTCHA widget and an optional detector prefetch. - **Trigger:** Importing the entrypoint; prefetch additionally requires a site key. - **Impact:** No concrete malicious effect was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T16:43:30.270Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint loads widget modules and, when activated, dynamically imports Prosopo packages to prefetch detector data. - **Rationale:** The manifest has no install lifecycle hook, and the inspected entrypoint’s imports and conditional prefetch align with a CAPTCHA widget. The scanner’s runtime bridge hint is not evidence of malicious behavior in the inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has build and test scripts but no install lifecycle hook., dist/index.js imports the package's virtual runtime and local widget modules; its dependency imports are Prosopo packages., The optional detector prefetch runs only when a site key is present and calls the Prosopo frictionless package. ## Affected versions and remediation This report applies to @prosopo/procaptcha-bundle@4.1.59. - Review the evidence and your use of @prosopo/procaptcha-bundle@4.1.59 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 L4: import { WidgetThemeResolver } from "./util/widgetThemeResolver.js"; L5: import { getWindowCallback } from "@prosopo/procaptcha-common"; L6: import { at } from "@prosopo/util"; ``` ### 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json has build and test scripts but no install lifecycle hook. Public source snippet (untrusted): ```json "scripts": { "clean": "del-cli --verbose dist tsconfig.tsbuildinfo", "build": "npm run build:cross-env -- --mode ${NODE_ENV:-development}", "build:cross-env": "vite build --config vite.esm.config.ts", "build:tsc": "tsc --build --verbose", "build:cjs ``` ### 9. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 91.0% - **Path:** dist/index.js - **Public source:** [View source]() dist/index.js imports the package's virtual runtime and local widget modules; its dependency imports are Prosopo packages. Public source snippet (untrusted): ```javascript import "./_virtual/_rolldown/runtime.js"; import { extractParams, getProcaptchaScript } from "./util/config.js"; import { WidgetFactory } from "./util/widgetFactory.js"; import { WidgetThemeResolver } from "./util/widget ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** dist/index.js - **Public source:** [View source]() The optional detector prefetch runs only when a site key is present and calls the Prosopo frictionless package. Public source snippet (untrusted): ```javascript flags) => { if (!siteKey) return; Promise.all([import("@prosopo/procaptcha-frictionless"), import("@prosopo/procaptcha-common")]).then(([frictionless, common]) => { frictionless.prefetchDetector(process.env.PROSOPO_ ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 14 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 14 - **Published dependency-graph edges:** 14 ### Published dependency entries - @emotion/cache 11.11.0 (Dependency) - @emotion/react 11.11.1 (Dependency) - @prosopo/dotenv 3.0.52 (Dependency) - @prosopo/locale 3.3.0 (Dependency) - @prosopo/procaptcha-common 2.11.33 (Dependency) - @prosopo/procaptcha-frictionless 2.13.15 (Dependency) - @prosopo/types 5.2.5 (Dependency) - @prosopo/util 3.3.6 (Dependency) - @prosopo/widget-skeleton 2.8.6 (Dependency) - dotenv 16.4.5 (Dependency) - fast-glob 3.3.2 (Dependency) - jsdom 25.0.0 (Dependency) - react 18.3.1 (Dependency) - react-dom 18.3.1 (Dependency) ## Package metadata - **Package:** @prosopo/procaptcha-bundle - **Ecosystem:** npm - **Version:** 4.1.59 - **License:** Apache-2.0 - **Version published:** 2026-08-20T12:33:23.412Z - **Package first seen:** 2026-07-01T04:11:03.863Z - **Package last seen:** 2026-10-31T16:04:01.912Z - **Known versions:** 50 - **Latest version:** 4.6.5 - **Appeal under review:** No - **Author:** PROSOPO LIMITED - **Maintainers:** christaylor, goastler, hughparry - **Runtime engines:** npm: ^11, node: ^24 - **Artifact files:** 104 - **Artifact unpacked size:** 605,915 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
