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 package has no install hooks, and its entry point only exposes widget functions. Network activity is part of CAPTCHA verification and begins through widget activation or an explicit caller option. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-04T11:59:49.856Z - **Finished:** 2026-11-04T12:01:07.366Z - **Download time:** 1025 ms - **Static scan time:** 220 ms - **AI review time:** 76264 ms - **Total time:** 77510 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 package provides a CAPTCHA widget that communicates with its provider to retrieve and submit challenges. - **Trigger:** A widget activation, an explicit procaptcha:execute event, or caller-supplied autoStart option. - **Impact:** No malicious behavior identified; the observed data flow supports the CAPTCHA verification feature. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T12:01:07.366Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The manager requests a challenge from a selected provider and submits the CAPTCHA solution with CAPTCHA-related behavioral signals and client metadata. - **Rationale:** The package has no install hooks, and its entry point only exposes widget functions. Network activity is part of CAPTCHA verification and begins through widget activation or an explicit caller option. ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports CAPTCHA widget mounting functions and declares no install lifecycle scripts., The entry point imports component modules and exports their functions; it does not invoke them at import time., Challenge startup follows widget activation or an explicit caller option such as autoStart., On submission, the CAPTCHA manager sends challenge data and CAPTCHA-related behavioral signals through the provider API. ## Affected versions and remediation This report applies to @prosopo/procaptcha-react@2.14.21. - Review the evidence and your use of @prosopo/procaptcha-react@2.14.21 before allowing it.
