Can sites accessing them through a phone browser find imei?

Question

Browsers

For example, I log in via wi-fi from an android phone through the Opera browser application on Facebook. Can Facebook find out the IMEI of my phone, can sites in general find out the imei of my phone through an android browser application (not the facebook app, etc.)?

MTS covered, the rest seem to still have vulnerabilities.
Answer: YES

Answer 2

just can’t do
a program on the phone, which you also provided access to yourself everywhere - this is not a browser that is generally a sandbox and all that
for everyone - look here
but no one has canceled the vulnerabilities - not the ones in the article https://habrahabr.ru /post/345852/, and some transparent call *#06# by a script
