Key findings
- Medium
Other
The bundled manifest declares Manifest V2 and includes permissions, but the published CWS manifest summary indicates Manifest V3 with only activeTab permission. This mismatch may indicate the listing was updated after extraction or a sync issue.
Analyst notes
The extension's code is a straightforward colour contrast checker that injects its own UI into pages via an iframe and uses chrome.tabs.captureVisibleTab for a color picker. It does not make any external network requests (the service worker is unregistered), and all data is stored locally using chrome.storage.local. The permissions and content script pattern are appropriate for its functionality. The ML model's regex hits are from normal minification, not malicious obfuscation.
