Risk Level:
Medium
Recommendation:
🟡 MEDIUM RISK — review
Top Risks
- webRequest + scripting + <all_urls>: can intercept and modify all browser traffic and inject code into any page.
- Privacy policy is Google's generic account policy — does not scope data collection to this extension at all.
- Developer uses free Gmail with no verifiable business identity; no verified publisher badge.
- Hex-string density in common.js suggests partial obfuscation; external host www.webtoolkit.info loads JS.
- No CSP declared (MV3 exemption applies, but combined with broad permissions increases attack surface on compromise).
Evidence
- broad_host_permissions manifest <all_urls> host permission paired with webRequest and scripting.
- generic_privacy_policy store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
- free_webmail_developer store Developer email sonthakit@gmail.com with no business domain; no verified publisher.
- hex_obfuscation crx common.js contains dense hex escape sequences flagged as likely obfuscation.
- external_js_host crx JS loaded from www.webtoolkit.info — third-party domain outside dev's control.
- no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
- maintenance_stale store Last updated January 2025; 17 months since update at scoring time.
- no_cve_findings crx cve_findings_raw is empty; no known vulnerable libraries detected.
Permissions Breakdown
- tabs medium Access to tab URLs and metadata.
- bookmarks medium Read/write all bookmarks — core function.
- downloads medium Can trigger file downloads; combined with scripting raises risk.
- storage low Local data persistence only.
- webRequest high Observe all network requests across all URLs.
- unlimitedStorage low No user-data risk, just quota.
- offscreen low Allows background DOM operations; low standalone risk.
- scripting high Inject scripts into any page via <all_urls> host permission.
- favicon low Read favicon URLs — matches stated purpose.
- <all_urls> high Broad host access amplifies webRequest and scripting to all sites.
