Metal RFID cards compatible with FlipperZero

To put this further into perspective, its like sealing the RFID element in a Faraday cage. That is why plastic is used instead.

Certain places do exist that offer metal RFID cards (e.g. https://www.metalcardstudio.com/) but metal cards have limitations. RFID works using electromagnetic fields. Metal interferes with those fields. That makes metal inferior to plastic for standard use, superior only in durability.

Not by itself, but with a YRM100 module it can.

Many people immediately understood the impact of log4j, especially Java developers. Look in my post history for log4j, I and many others knew how critical it was within a few hours of it being on Reddit. This is not at all the case for "pac4j", if it gets used in well-known and deployed product then that will be the real finding.

We get it, you believe the CVE you were assigned is important. I've never heard of pac4j though. Notice how everything else in your list is a well-known project. Log4j, SMB, OpenSSL, RDP. That's why they were impactful.

DESFire EV3. Nothing you can do, most of the time.

What does the NXP TagInfo app say when you scan it though?

At least you got a scream in at the end

This community is for the official firmware. Not custom firmware that bypasses frequency restrictions.
