Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Vidava [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• <all_urls> host permission + content scripts on every page including checkout/payment pages handles sensitive financial data.
• Developer domain vidava.ai does not resolve — accountability gap for a financial AI extension.
• Privacy policy admits data collection and third-party sharing but lacks retention disclosure.
• innerHTML DOM sink in overlay JS is a XSS risk on pages where extension injects content.

Evidence

• host_permissions_all_urls manifest <all_urls> host permission combined with content_scripts on all URLs; runs on every site visited.
• developer_domain_not_resolving api threat_intel: vidava.ai domain does not resolve — no live accountability surface for developer.
• privacy_policy_no_retention api Policy fetched; scope_extension=true, data_collection=true, third_party_sharing=true, retention=false.
• dom_xss_sink crx vidava-overlay.js: setBody(html){body.innerHTML=html} — unescaped variable into innerHTML, XSS risk.
• install_perm_anomaly store 5 installs with high-tier permission (<all_urls>); small_install_high_perm=true.
• js_external_hosts crx Extension contacts payjfhkpnsmyawugymfl.supabase.co, vidava.app, www.jsdelivr.com.
• no_csp manifest MV3 extension with csp_present=false; dom_sink_innerhtml_userctrl finding elevated by FIX B.
• unverified_new_developer store Not verified publisher, not featured, no ratings, domain non-resolving, 5 installs only.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Vidava [adware] + malext.io malicious_extension_sentry; score 3.74 -> 6.24 (+2.5 cap 2.5).

Permissions Breakdown

• storage low Used to persist extension state locally; low standalone risk.
• activeTab medium Grants access to current tab on user action; scoped but pairs with <all_urls>.
• tabs medium Can read tab URLs and metadata across browser; moderate surveillance surface.
• <all_urls> (host_permission) high Content scripts injected on every site; reads checkout pages including payment data.
