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. The package mounts a browser captcha widget and conditionally prefetches its provider after a caller supplies a site key. - **Trigger:** A host page renders a Procaptcha widget with a site key. - **Impact:** No unconsented install-time mutation, file access, command execution, or package-level data exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:14:22.381Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser captcha rendering and provider prefetch. - **Rationale:** The flagged environment access configures the captcha widget, while the bundled dependency imports are ordinary declared dependencies. Source inspection found no lifecycle hook or concrete malicious behavior. ### 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 lists build and test commands but no install lifecycle hook., The published entry imports declared Prosopo and UI dependencies normally., Runtime prefetches the declared captcha provider only after a site key is supplied., Environment values are used as captcha configuration fields, not read from files or sent by this package. - **Evidence against:** No package code invokes shells, writes files, harvests credentials, or exfiltrates data., The static dependency-bridge finding is explained by normal imports in the bundled entry point. ## Affected versions and remediation This report applies to @prosopo/procaptcha-bundle@4.4.2. - Review the evidence and your use of @prosopo/procaptcha-bundle@4.4.2 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 lists build and test commands 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 ${NODE_ENV:-development}", "build:cross-env": "vite build --config vite.esm.config.ts", "build:tsc": "tsc --build --verbose", "build:cjs": "NODE_ENV=${NODE_ENV:-development}; vite build --config vite.cjs.config.ts --mode $NODE_ENV", "typecheck": "tsc --project tsconfig.types.json", ``` ### 9. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** dist/index.js - **Public source:** [View source]() The published entry imports declared Prosopo and UI dependencies normally. Public source snippet (untrusted): ```javascript import "./_virtual/_rolldown/runtime.js"; import { extractParams, getProcaptchaScript } from "./util/config.js"; import { resolveStartMode } from "./util/startMode.js"; import { WidgetFactory } from "./util/widgetFactory.js"; import { WidgetThemeResolver } from "./util/widgetThemeResolver.js"; import { getWindowCallback } from "@prosopo/procaptcha-common"; import { PROCAPTCHA_START_EVENT, StartModeEnum } from "@prosopo/types"; import { at } from "@prosopo/util"; ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/index.ts - **Public source:** [View source]() Runtime prefetches the declared captcha provider only after a site key is supplied. Public source snippet (untrusted): ```typescript if (!siteKey) return; if (flags.startMode === StartModeEnum.manual) return; void Promise.all([ import("@prosopo/procaptcha-frictionless"), import("@prosopo/procaptcha-common"), ]) .then(([frictionless, common]) => { frictionless.prefetchDetector( process.env.PROSOPO_DEFAULT_ENVIRONMENT as EnvironmentTypes, common.pickIpMode(flags), siteKey, ); }) .catch(() => undefined); ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/util/configCreator.ts - **Public source:** [View source]() Environment values are used as captcha configuration fields, not read from files or sent by this package. Public source snippet (untrusted): ```typescript const siteKey = options.siteKey || process.env.PROSOPO_SITE_KEY || ""; return ProcaptchaConfigSchema.parse({ defaultEnvironment: process.env.PROSOPO_DEFAULT_ENVIRONMENT ? EnvironmentTypesSchema.parse(process.env.PROSOPO_DEFAULT_ENVIRONMENT) : EnvironmentTypesSchema.enum.development, userAccountAddress: userAccountAddress || "", account: { address: siteKey, }, serverUrl: process.env.PROSOPO_SERVER_URL || "", mongoAtlasUri: process.env.PROSOPO_MONGO_EVENTS_URI || "", ``` ## 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 11.14.0 (Dependency) - @emotion/react 11.14.0 (Dependency) - @prosopo/dotenv 3.0.55 (Dependency) - @prosopo/locale 3.4.1 (Dependency) - @prosopo/procaptcha-common 2.13.1 (Dependency) - @prosopo/procaptcha-frictionless 2.16.0 (Dependency) - @prosopo/types 5.8.0 (Dependency) - @prosopo/util 3.3.9 (Dependency) - @prosopo/widget-skeleton 2.8.7 (Dependency) - dotenv 16.4.5 (Dependency) - fast-glob 3.3.3 (Dependency) - jsdom 25.0.0 (Dependency) - react 19.2.8 (Dependency) - react-dom 19.2.8 (Dependency) ## Package metadata - **Package:** @prosopo/procaptcha-bundle - **Ecosystem:** npm - **Version:** 4.4.2 - **License:** Apache-2.0 - **Version published:** 2026-09-08T11:43:10.465Z - **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:** 136 - **Artifact unpacked size:** 634,769 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
