Top Risks

  • declarativeNetRequestWithHostAccess + <all_urls>: can silently intercept/redirect every HTTP request across all sites.
  • Content scripts injected into every page combined with broad host access enables DOM reading/manipulation at scale.
  • Privacy policy is Google's own account policy — wholly unscoped to this extension; admits data collection and 3rd-party sharing.
  • Free-webmail developer (gmail), no verified publisher, no business website — unaccountable identity.
  • install_url_hijack detected: extension opens a URL on install to an unverifiable target.

Evidence

  • declarativeNetRequestWithHostAccess + <all_urls> manifest HIGH capability to block/redirect any request on any site; disproportionate for tab-snooze function.
  • content_scripts_matches=<all_urls> manifest Scripts injected into every page the user visits — broad DOM access with no scoping.
  • install_url_hijack=true manifest onInstalled opens external URL; target unknown.
  • privacy_policy_classification crx Google account policy: scope_extension=false, data_collection=true, third_party_sharing=true — D rule applies → +10.0.
  • developer_email=hunkiepeanut.dev@gmail.com store Free webmail, no verified publisher, no business domain — reputation floor applies.
  • js_external_hosts includes foo.bar and example.com crx Suspicious/placeholder hosts contacted; aim.cloudflare.com and speed.cloudflare.com are non-standard Cloudflare endpoints.
  • csp_present=false (MV3) manifest No explicit CSP; MV3 provides defaults but no additional penalty per rubric.
  • no install_count store Install count missing — blast radius unknown; no social proof.

Permissions Breakdown

  • alarms low Core function: schedule tab re-open events.
  • storage low Stores snooze schedules locally.
  • contextMenus low Adds right-click snooze option.
  • tabs medium Can read URLs and titles of all open tabs.
  • declarativeNetRequestWithHostAccess high Can intercept/redirect network requests on all URLs; very broad for a tab scheduler.
  • <all_urls> (host) high Full host access across every site; combined with declarativeNetRequestWithHostAccess is critical.
  • <all_urls> (content_scripts) high Content scripts injected into every page — can read/modify DOM on any site.
