1	Data Exfiltration	critical	js/subData.js (line 22)	Every video download triggers a POST to the operator's server at bm-com.com/api/DouYinDdownlog, transmitting the video URL, image URL, title, creator name, extension version, and the user's auth token. This systematic…	1.4.1
2	Tracking	critical	js/background.js (line 46)	The background service worker calls `userDownlog()` on every startup (unconditionally, without user action), sending the auth token to bm-com.com to sync a download counter. The `upDownLog` function additionally sends…	1.4.1
3	Credential Theft	high	js/login.js (line 73)	The registration flow transmits the user's password in plaintext (`password: a, password2: n`) to bm-com.com/api/sigin. Unlike the login flow which applies MD5 hashing, registration sends the raw password directly ove…	1.4.1
