Yeah, eight SSL Intermediate Certificates of eMudhra have been publicly leaked. All your servers https traffic can be broken right now. Browsers are fine as they have revoked the certificates but as you can see, curl and many other libraries still accept those.

No download can be trusted right now. Remember to not only patch your main systems but every docker container you run.

This is bad 😅

Dammit, Firefox on android hasn't been updated. Chrome did, thankfully

this is odd, your comment prompted me to try myself, and while Firefox on Android does properly block the request on my personal profile, it doesn't seem to block them on my work profile. anyone got a clue what could be the issue here?
